There can be a number of reasons for this issue. For e.g. use of incorrect cable and USB dongle, drivers not installed properly, damaged load cell or interface, obsolete operating system etc. Please review the possible causes and remedies for this issue on our Blog - "Troubleshooting connectivity issues with Loadstar Sensors' sensors or interfaces" to try and resolve this issue on your own. If you still cannot, then contact us for support.

No. Sensors and interfaces are not plug and play. Each sensor must be calibrated with a specific sensor and used together as a pair. You cannot simply mix and match sensors and interfaces. Once calibrated, each pair must be identified with a matching serial number label and used together. If a load cell or sensor goes bad, then the replaced item must be once again labeled and identified after calibration together to avoid any issues during use.

Yes. Every load cell and interface must be mated and calibrated before they are functional. They are not readily plug and play. That is why for new purchases, we insist that you add a calibration service to your order when ordering a sensor and an interface. That way, we make sure you get a NIST traceable calibration certificate and we make sure the sensor meets specifications before we ship it to you. When you get the kit, it is ready to use out of the box.

For future orders, one can get it calibrated by third party calibration shops if they have the software, or you can do it yourself if you have the calibration utility built into LoadVUE Pro, SensorVUE and ControlVUE software. We offer calibration services with NIST traceability that meets most QA/QC needs. You can refer to our calibration build and buy page to see the various calibration options we have and their respective prices. 

If you register and login to our site, on most load cell pages, you can find a Build Your Order button. On that page, you can add items to your cart and either place an order to buy it or have a formal quote sent to you.

Alternatively, you can contact us with the desired items for a quote and provide us your full shipping address and phone number. We will be happy to send you a formal detailed quote with shipping costs, expedites options, lead time and payment fees etc.

3D models as well as Spec Sheets of most of our load cells are available on the detailed web pages for each sensor. You can usually jump to it by clicking on the quick access button on that page. You can also access it under the Support Menu option on our site. You must register and login before you can access and download these files. If you do not find what you need, please contact us.

LoadVUE Lite (LV-100 and LV-400) is compatible with Windows 8/10/11 and Mac OS as well as Linux (Raspberry Pi). LoadVUE Pro, SensorVUE, and ControlVUE are compatible with Windows 8/10/11 versions. 

One each load cell page, we make available options to build your own kit. You can build a digital USB kit by adding a load cell, an interface (DI-100 or DI-1000 or DI-400), software, high speed options, wireless options, accessories and calibration. All cables and dongles required for operating the load cell, interface, and software are typically included in the kit (for e.g. a USB kit with DI-100U will come with a miniB to miniB cable and an S2U Serial to USB dongle). The wireless kit has a battery operated, rechargeable wireless interface (DI-1000ZP) which also has a USB output port.

The Analog kit typically consists of a load cell, an analog interface with 0-5 VDC output (AI-1000) or 4-20 mA output (AI-1000-CV), and analog calibration in compression, or tension or universal mode.

Please take a look at this video to get an idea of the various kits we offer. A kit with calibration service includes a calibration certificate.

If you want any more information about a specific kit, please contact us with the kit details. 

For most kit orders which includes a sensor, an interface, calibration and software, the typical lead time is 2 weeks after receipt of order with payment or a PO. This is because we need to kit the order, calibrate it, pack it and ship in the order in which it is received.

For most sensor only orders without calibration, we can ship within a few days. If needed urgently, we offer expedited processing options with a 1 week, 3 business day, 1 business day or same day options for a small additional fee. The Build Your Order buttons on a sensor page typically lays this out in detail for you.

For special cases, please contact us.

We require pre-payment for most orders unless payment terms have been setup. For domestic US customers, one can apply for terms by filling out a form and providing references. For international customers we require pre-payments prior to shipping out the order.

Payments can be made with a credit card or Paypal (3.5% payment fees of total), wire transfer ($40 for domestic and $65 for internationl payments), or via Checks (domestic customers only) or ACH at no additional cost. We will not start processing the order unless we get an approved PO or payment. The lead time starts after the payment or an approved PO is received.

Maximum Input Voltage = 5V Input Voltage Noise < 100µVrms Input Current = 50mA max

Generally speaking iLoad series load cells are designed to be used in a static loading situation. The load cells perform well in a dynamic environment as well but are limited to approximately 3 to 5 millisecond response times.

If you are looking for faster response rates you can utilize one of our resistive analog load cells in combination with our DI-1000UHS-1K digital USB interface with data output rate of 1 khz to capture faster dynamic forces with our LoadVUE Pro, SensorVUE or ControlVUE software.

As far as true impact force measurements are concerned, we offer a complete solution with a resistive force sensor, a DI-1000UHS-10K USB interface with up to 50 khz data rates and LV-1000HS-10K software to capture, display and plot data on a Windows PC or Tablet. Please review our Impact Force Measurement page for further information.

You can use any of our iLoad Series load cells with the optional 0-5V analog output. You can also use any of our resistive load cells with the AI-1000 Single Channel Load Cell Signal Conditioner which provides a 0-5V output that can be input directly into most DAQs or PLCs. We also offer a 4-20 mA output via the AI-1000-CV analog signal interface.

Yes we provide calibration data that shows the applied load vs. measured loads using our load cells. For analog load cells, we supply a calibration curve that shows load vs. voltage.

The iLoad Analog series load cells have a linear output with approximately 0.5V at zero load and approximately 4.5V at full load.

The S2U adapter converts Serial TTL (UART) signal from the following devices to USB signal; the USB still appears as a virtual COM port to Windows/Linux/Mac applications. Please visit this page for the latest drivers.

• DI-100U
• DI-400U internally uses 4 S2U adapters.
• DQ-1000U
• DQ-4000U
• DS-4000U
• iLoad, iLoad TR and iLoad Pro series load cells.
• The DI-1000U does not need this adapter.

• When the load cell or the digital USB load cell interface is connected to the computer, does an USB port show up in the device manager?
• If the answer is No, then the drivers may not have been properly installed. Please download and install the drivers from this page.
• Some devices and load cells need an S2U adapter (dongle) to convert the signal from the device into USB. See the answer to the previous question. Make sure you are using this adapter from Loadstar Sensors. You cannot use a off-the-shelf standard USB-A-male to mini-B-male cable with these devices. Our S2U adapter contains proprietary electronics to perform the serial to USB conversion.
• The DI-1000U does not need this adapter. So an off-the-shelf cable can be used with DI-1000U. Do not use the S2U adapter with the DI-1000U.
• If the COM port shows up on the device manager, but the software still does not recognize the device then check the cable connections to make sure they are tight. If necessary, try replacing the cable.
• If the problem is with the DI-100, is the led on the DI-100U blinking? If yes, the dongle and the cable are providing power to the unit. If not try replacing the dongle or the cable or both.
• Some DI-1000U units have an on-off switch. Is it on?

Yes. Although we don't recommend it, we can splice a cable to extend the length. 

Instead of extending the cable between load cell and the interface, we recommend that you extend the output side i.e. the USB output cable by using our USB Extender cables with 5m (15 feet) per cable that can be daisy chained up to 45 feet total. 

Each load cell has a rated capacity or max load. Most have a safe overload limit of 50% of rated capacity. (e.g. If a load cell is rated to 1,000 lbs, then you can safely use it occasionally to 1,500 lbs.) However, we recommend you use the load cell within the rated limit indicated on its spec sheet. Overloading your sensor will damage it.

If you think you overloaded your load cell, please send your load cell, interface, and cables back to us ASAP. We will have to evaluate the load cell to see if it has been damaged. You will have to replace the load cell if it has been damaged.

Please also fill out a support form with the issue and sensor serial number to help us better assist you.

Assuming you mean with regard to the DS-3000-Pro display or the LV-100 and LV-400 LoadVUE Lite software, 1-channel means it can only connect to 1 sensor (digital load cell or digital load cell kit) at a time, and 4-channel means it can connect up to 4 such digital load cells or load cell kits at a time.

After signing up and logging into our website, you can find the solid models under the Support menu option on the top task bar or through thinks link

The output signal from the sensors are very small mV/V outputs. If the magnet induces an electro-magnetic effect on the output signal, it could affect the results of the sensor and appear as noise. Sometimes you can simply use statistical techniques like median or averaging filters to smooth out the noise.

However, our capacitive sensors are much less affected, if not at all, affected by external electromagnetic fields. This is because the entire sensor is enclosed by a faraday cage.

To minimize noise: turn off all cell phones, plug the interface power supply into its own outlet, and keep the interface, sensor, and cables away from other electronics (fans, pumps, transformers, etc.) that can produce electromagnetic noise.  

Yes, but only for the iLoad, iLoad TR and iLoad Pro Digital USB load cells – not the iLoad Analog load cells. You would need to provide a 5V regulated power supply to the iLoad Analog load cell. Any offset from this voltage will cause a similar offset in the output voltage.

In general, most iLoad Series load cells have three threaded holes on the base for ease of mounting. Most have a threaded hole on top or a threaded stud on top of the load cells for ease of fastening to an upper surface. We offer a variety of adpaters, leveling feet, platforms, load buttons and other accessories which make it easy to build a variety of applications with readily available parts.

You can also refer to the mounting option description on the respective iLoad webpage you are interested in. For the exact sizing of the iLoad, you can login and refer to the iLoad Spec Sheet. 

At the present moment we recommend that you take care NOT to apply side loads as it will affect accuracy of the results.

For the iLoad, iLoad Pro and iLoad TR Series load cells - all the necessary signal conditioning, digitization and communication electronics are built into the load cell package. For the iLoad Mini Series load cells, some of the electronics are built into the DQ-1000 (single channel load cell interface) and the DQ-4000 (four channel load cell interface).

The iLoad Digital USB has a Mini-B connector. The baseline output from the sensor is a Serial TTL output which is converted into a USB signal using a USB dongle device that can be added to the end of the Mini-B connector.

In theory a typical PC can support up to 255 serial devices (COM ports), but in practice this is limited by the specific configuration of your PC's hardware. Since the iLoad Digital USB load cell appears as a virtual COM port on the PC, up to 255 such load cells could be connected to a single PC as long as the PC is able to supply the needed excitation voltage.

Each iLoad Digital USB load cell needs 50mA at 5V and a PC's USB port is typically able to provide upto 100mA at 5V. So you can power at least one iLoad Digital load cell per USB port. Since some PCs have limited USB ports, you can use a powered USB hub to expand the number of load cell you can plug to a PC.

If you use our SC-1200 interfaces, you can connect up to 12 iLoad Series serial sensors (baseline output without our USB dongles at the end of the cable) directly into the SC-1200 and read data from all of the connected load cells via USB, RS-485 or IEEE 802.15.4 wireless protocols. the SC-1200 supplies all the power needed to power up to 12 sensors. In addition, each SC-1200 can accept inputs from up to 4 other SC-1200s! This way you can construct a hierarchical network to support thousands of load cells.

One important limitation of the SC-1200 you need to keep in mind is that it was designed to allow data collection from connected sensors at the rate of about 0.5 seconds per port. Hence it could take up to 6 seconds to sample data from all twelve connected sensors. Hence it is not ideal for applications that require fast responce times. For those applications just use a 4,7,10 or 12 port USB Hub available from us or other vendors such as Belkin, NetGear and others.

Our iLoad Digital USB load cell is plugged into a PC's USB port and shows up as a COM port (serial port) and responds to an ASCII command set. So any program that can communicate with a serial port can communicate with our load cell and retrieve the load values.

The iLoad Series load cells are temperature compensated in the operating temperature range if the rate of change of temperature is gentle (less than 1 degree C per minute). Sudden changes in temperature (“thermal shock”) can cause temporary compensation errors.

Despite the compensation scheme, however, due to accumulation of errors over a period of time, errors can add up to several percentage of full scale if used without “tare” over a few days. Long term stability is very difficult to achieve under changing thermal conditions, so we recommend periodic ‘tare’ on the load cells to reset the zero value at the new temperature condition.

The iLoad Mini load cells has 2 frequency outputs. When Control Input = logic ‘1’, the Mini outputs the load cell frequency, Fsensor. When Control Input = logic ‘0’, the Mini outputs the reference frequency, Fref. The compensated frequency Fcomp = Fsensor - K*Fref, where K is a constant provided by Loadstar. Loadstar can provide the coefficients for the quadratic equation to translate Fcomp to weight. Although possible in theory, most customers do not have the equipment, skill or time to perform calibration in their facility, hence we recommend that you purchase the Mini Load Cells with the DQ-1000 or DQ-4000 interface devices.

This can be tested by launching the Hyperterminal application from Windows XP, opening up the relevant COM port and sending the command "O0W1". The load cell will return the sensed load in millipounds as an ASCII string. LabVIEW or Matlab can retrieve this string and process the result. See Driver Installation and Hyperterminal Operation for more information and examples using LabVIEW and Matlab.

You can use a 9V battery with a regulator to regulate down to 5V from 9V. You just have to be careful that the battery doesn't deplete down to below 5 V since the output signal will then start dropping with the drop in voltage.

The iLoad Analog load cell has a USB MINI-B connector.

• Pin#1 = 5V power (Red wire) 
• Pin#2 = Data - (White wire) 
• Pin#3 = Data + (Green wire) 
• Pin#4 = 0 to 5V Output (Yellow wire) 
• Pin#5 = Ground (Black Wire)

No. However, an offset at the input power would cause similar offset in the output voltage.

The CS Series load cells is superseded by the iLoad Analog series of load cells. The iLoad Analog load cell has two important improvements:

Deterministic outputs
The CS Series load load cell had a 2V window of output voltages in the 0-5V range. However the output voltage at zero load could be anywhere in the 0.5 to 1.5V range and the output voltage at the full scale load could be anywhere between 2.5V to 4V. This made it difficult for an end user to write programs deterministically.

The iLoad Analog load cell is always close to 0.5V at zero load and always close to 4.5V at full scale loading. When you purchase an iLoad Analog load cell from us, we provide a calibration equation that provides a conversion between voltage and force applied. This lets a programmer to deterministically set levels at which certain actions are taken.

Temperature Compensation
The CS Series load cell was a purely analog load cell with temperature compensation performed in the analog domain.

The iLoad Series is built on a digital platform and has a microcontroller and a temperature sensor inside the load cell. The environmental compensation is done in the digital domain and is far superior to the results of the earlier design leading to better stability with temperature and time.

For customers who purchased a CS Series load cell - we recommend an upgrade to the iLoad Analog series - or better still to the iLoad Digital USB series of load cells with the optional analog output. Please call us for help in moving to the new series.

DI-100U/DI-100UHS or DI-1000U/DI-1000UHS USB Interface have USB outputs for resistive sensors.  (Note: You need to calibrate the sensor and interface together for the pair to function) You can refer to our interface products page for a more detailed breakdown of our various interfaces. 

If you want an Analog 0-5V DC output, then add Ai-1000. If you want an Analog 4-20 mA output, then add AI-1000-CV. It is important to note that you also need analog calibration for the sensor and interface pair to fuction. Here is a link to read more about our analog interfaces. 

The biggest difference between both interfaces is resolution and accuracy. The DI-100 has a 16 bit ADC while the DI-1000 has a 24 bit ADC for much greater resolution. Additionally, the DI-100 has an accuracy of ±0.1% and the DI-1000 is accurate to ±0.02%.

Both the DI-100 and DI-1000 are powered via the USB port of your PC. The only exception is the DI-1000ZP which has a battery backup.

The DI-100U supports four wire load cells with outputs from 1 - 3 mV/V. The DI-1000U supports four and six wire load cells with outputs from 1-25 mV/V.

The data update rate depends on the model. Please see our interfaces page for detailed comparison of features, data update rate, etc.

Our wireless interfaces [DI-1000ZP, DI-1000BLE, DI-1000WiFi] need to be charged or plugged in with a power adapter for proper operation. One full night’s charge offers a minimum 2 hours of operation. The switch can be turned on/off to extend use over a long time as needed. 

When charging, please keep the switch in the "ON" position. The interface will not charge if the switch is “Off.”

Yes, we provide drivers for several different platforms including Windows (8, 10, and 11), Mac OS and Linux. Since we use the industry standard FTDI chips to convert serial output from our load cells and interfaces to USB output, any platform that supports these FTDI chips will be able to read our devices. Please visit http://www.ftdichip.com/Drivers/VCP.htm for the latest drivers for your platform.

Once the drivers are installed, the device appears as a virtual COM port to the system (similar to a Bluetooth device). The device then can be read with any terminal or modem program that can read serial ports.

Note: iLoad series load cells purchased prior to March 2009 will only work with 32 bit versions of Windows XP. If you have these load cells starting with serial no. F09xxxxxxxx then, you must contact us to purchase replacement load cells. 

You do not necessarily need the software to use these load cells. If you have a terminal emulator, such as Putty you can issue commands and obtain load in millipounds directly. But we recommend that you purchase one of our software products such as LoadVUE Pro to display, log, and plot the sensor data.

Please see the detailed load cell software pages to get more information about the various versions of our software.

Please see the detailed load cell software pages to get more information about the various versions of our software.

If you are having difficulty connecting your digital load cell or interface using our LV-100 or LV-400 LoadVUE Lite software, there could be an interference issue with another non-Loadstar Device. You need to uninstall that device before using Loadstar's sensors. Please take a look at this Support note written specifically for this purpose.

Our LoadVUE Pro 1000 software provides a convenient means to easily log and plot force data. Other versions with more features are available as well.

Our iLoad Digital USB load cell is plugged into a PC's USB port and shows up as a COM port (serial port) and responds to an ASCII command set. So any program that can communicate with a serial port can communicate with our load cell and retrieve the load values. Please see our downloads page for code examples.

In theory, there is no limit. But for the sake of preventing computer lag, 15-20 sensors is recommended. There are also practical limits based on your PC's computing ability and free RAM. We recommend at least 16 BG for SensorVUE.

You can refer to our software spec sheet to read more about the software features.

You should have a minimum of 16 GB of RAM, 1 GB of hard drive memory space, and Microsoft Windows 8/10/11. You can also refer to our Software Spec Sheet to see other software requirements. 

Our software download links are only available up to one year from date of purchase. Since we are constantly making updates and changes to the software to fix bugs, our policy is to ask you to purchase a new copy of the software if you need to download again after one year.

Please contact us if your purchase was within the last 12 months. 

Yes. Our SensorVUE and ControlVUE software allows you to display real time data simultaneously. You can also take a look at our software spec sheet to see the various features offered on our SensorVUE and ControlVUE software.

Our software is only compatible with Loadstar Sensors digital sensor kits.

Yes. You can use ControlVUE software to control external devices based on sensor values or values derived from raw sensor values to turn ON or turn OFF external devices.

No. At the moment, all our software offerings are a one time purchase for the license. The software can then be used one a single PC. If needed we can provide a download link that will be available up until 12 months from purchase. After 12 months, if you lose your original USB Stick then you will need to buy a new license.

Please contact us if you would like to purchase a new license or if you need a redownload link. 

Our software is subject to our end user license agreement that states you can install purchase software up to one PC or Tablet per purchaed license. Here is our software policy page for you to refer to. 

You can change the unit of measure, display resolution etc by finding the menu option for "Options."

Yes. You can do it one of two ways. One is by using the Overlay Feature. You can select data from two different log files and overlay them over each other for comparison. Or you can download your logged data into an Excel file and bring both into the same file and then compare the data in Excel.

No. LoadVUE Pro is only compatible with force sensors. For torque and displacement load cells, please purchase SensorVUE which supports displaying, logging and plotting data from multiple sensors as well as multiple types of sensors.

No. LoadVUE Pro is only compatible with force sensors. For torque and displacement load cells, please purchase SensorVUE which supports displaying, logging and plotting data from multiple sensors as well as multiple types of sensors.

Per our software policy, you can only install our software on one PC/tablet per license. You will need to purchase another copy of the software for a new PC/tablet.

However, if you wish to uninstall the software from the original PC, you can do so and install on a new PC using the USB Drive, on which you have the installation file. If you do not have the software on a USB Drive, then for up to 1 year from the date of purchase, we can send you a link to download and install the software.

Please read more about our software policy here. 

If you buy a resistive load cell only, you will get a nominal mV/V Output e.g. if you supply 10 V to the load cell, then the change in output from zero load to full load will be about 20 mV if the load cell has a 2 mV/V rating. But, it is not a "real" or "accurate" representation of the actual mV/V for that particular load cell.

If you want an actual mV/V value you must add an analog mV/V calibration, in Compression, Tension, or both (Universal) to your order.

If you want USB Output, add a DI-100U/DI-100UHS or DI-1000U/DI-1000UHS USB Interface and Digital Calibration in Compression, Tension or Universal mode to your order.

If you want an Analog 0-5V DC output, then add AI-1000 and an Analog Calibration in Compression, Tension or Universal mode to your order.

If you want an Analog 4-20 mA output, then add AI-1000-CV and an Analog Calibration in Compression, Tension or Universal mode to your order.

Here is our calibration page that provides more information about our calibration service and the costs. 

Yes. A sensor and interface pair needs to be calibrated together to be functional and used together as a pair. They are not readily plug and play.

Here is our calibration buy and buy page to see our various offerings and pricing.

Please contact us with a picture of the sensor and spec sheets, so we can determine if we are able to calibrate it. If we are able to calibrate the load cell, we will send you a quote.

We highly recommend you send us your load cells for calibration. Calibration is a very precise process that requires delicate care for accurate results. Our team of engineers is highly experienced in calibrations, and we use state of the art equipment traceable to NIST standards, references, and dead weights to perform calibrations. Letting us calibrate your load cells will guarantee accurate results. If there is anything wrong with your existing load cells, we can also easily let you know and issue a replacement to minimize lead time. 

You can refer to our calibration service page to see the various calibration options and prices available

Please make sure to purchase a recalibration order and then use the Invoice number as the RMA number prominently on your shipment box. And only then, ship the load cell sensor, interface, and cables to 48521 Warm Springs Blvd #308, Fremont, CA 94539.

The answer depends on your application, QA/QC requirements of your organization and how frequently you use and perhaps misuse the sensor.

At a minimum, we recommend recalibration at least once every year if you use the sensor moderatly. If you suspect the sensor is not behaving as expected, we recommend you check the results carefully and and send it in for inspection and recalibration immediately. You can check how inaccurate a sensor is by simply placing a known dead weight on it and checking if it is within the +/- accuracy specs for the load cell.

Yes, please send the sensor, interface, and cables back for recalibration. The calibration coefficients are burned into the Interface Device, so the sensor and interface MUST be used together as a pair. We label both with the same Serial Number in order to identify the two as a pair.

Yes. Please indicate if you want "As Received" verification services when making your order. You can go to our calibration and recalibration build and buy pages to see the costs. 

If you want "As Received" verification, please select an additional quantity of the same calibration you want.

We charge $100 for an evaluation. If we find that the load cell/interface needs replacement, the $100 evaluation fee will be applied towards your new purchase.

We recommend sending in your load cell and interface pair for calibration if you don't have the correct tools and fixtures, or have expereince doing it yourself to prevent damaging the load cell or improper calibrations.

However, if you want to calibrate your sensor yourself, you can apply known values with the utility tool present in the LoadVUE Pro, SensorVUE or ControlVUE software to read raw digital values, compute calibration coefficients and burn it into the interface. Here's our page on calibration/recalibration, which sheds some light on our calibration process, as well as videos on calibration

Load cells that have yet to be calibrated typically come with a mV/V rating (e.g. 2 mV/V). This means that if you apply 10V power to the device, the maximum change in output for full rated applied force is 20 mV (10 V x 2 mV/V = 20 mV). 

If the sensor is rated to 100 Nm, the output will change from 0 mV to 20 mV proportionally. So, if a 50 Nm force is applied, you will get 10 mV as the output signal.

You can either purchase directly on our website under your desired sensor's build and buy page, or purchase through our partners: McMaster, Digikey, Amazon, or Jameco

We do not have ISO certification at the moment but are working to get one. However, for calibration, we use reference load cells that were calibrated at a ISO 17025 certified calibration lab, and we use NIST traceable equipment.

We offer some NTEP certified resistive load cells in some configurations and capacities such as the RRP1 and RRP2 Single Point Load Cells and the RRS1 S-Beam load cells. The RSP1 Single Point Load Cells are OIML approved. These resistive load cells are sourced from reputable third parties who have been building resistive load cells for a long time.

Our calibrations use references that are NIST traceable. The certificates include this traceability information.

Although we do not have ISO certification at the moment, our calibration process ensures quality for our customers. For calibration, we use reference load cells that were calibrated at a ISO 17025 certified calibration lab, and we use NIST traceable equipment.
