Compatible with PC, Mac, and Linux Devices. Recommended PC or Tablet Requirements:

• Windows compatible PC or Tablet (8/10)
• 1 TB disk space
• 8 GB memory
• At least Dual-Core Processor

• These USB or Wireless Sensor Interfaces Work with bridge type devices with mV/V outputs
• Supported devices include resistive load cells, torque sensors, pressure sensors etc.
• The DI-100U works with devices up to 3 mV/V with a fixed gain setting and offers accuracies up to +/- 0.1% of full scale
• For most applications the DI-100U offer a simple low cost solution to connect load cells to a PC/Mac/Linux processor

Click here for an example on how to interface the DI-100U to an Arduino microcontroller. In order to make it easy to access the Tx, Rx pins and connect it to an Arduino or other micro-controller, we offer the HX-100 break-out board that gives access to those pins without destroying the ability to use the S2U for USB access.

The DI-100 is meant for 4 wire (E+, E-, S+, S-) devices that output no more than 3 mV/V or in other words if 5V power is supplied, then the max output from the sensor is 15 mV.

There is a terminal block inside the interface device (under the lid) with screw terminals to connect the sensor. The pinouts are as shown below:

The DI-400U 16-bit USB Load Cell Interface has the ability to interface with up to four resistive load cells with mV/V output.  When connected to a PC, the DI-400U appears as four individual DI-100U devices with four Virtual COM ports. This is essentially a four channel version of the DI-100U. It enables a user to quickly connect up to four 4-wire load cells to this interface, digitally calibrate each and then obtain calibrated force/load/weight values from all four connected load cells via a single USB output.

SensorVUE, ControlVUE both can display, log and plot data from all four connected load cells.

This is the easiest way to build a scale with four independent measurements at the four corners of a frame/platform. By using this solution, you can save time, money and the headache of using a junction box and performing an analog summation from multiple load cells since each load cell is digitally calibrated and calculated weights/forces are summed digitally!

• DI-400U offers about 40 Hz max data rate from each channel
• DI-400UHS offer about 250 Hz max data rate from each channel for higher speed applications

Use SensorVUE to read, display and log and plot data from all four connected load cells and ControlVUE to control external devices based on sensor values. SensorVUE and ControlVUE are compatible with Microsoft Windows 8/10 on a PC or Tablet.

• The DI-1000U works with devices up to 2 to 25 mV/V with a variable gain setting
• Offers high accuracies up to +/- 0.02% of full scale
• Compatible with NTEP and OIML Load Cells and Scales used For Trade applications

The DI-1000 is a digital interface with a 24-bit ADC that makes it easy to connect a sensor to a PC via USB or Wireless protocols. It can handle inputs up to +/- 2V with a variable gain setting that can be set depending on the type of signal available and provides a native USB output and an optional wireless output.  There is a terminal block to connect the external sensor to it more easily than in the case of the DI-100U.

It comes in many flavors:

• DI-1000U, DI-1000UHS, DI-1000UHS-1K and DI-1000UHS-10K for Wired USB Output for max 60 Hz, 500 Hz, 1KHz and up to 50 KHz respectively
• DI-1000ZP with USB and Wireless Point to Point 802.15.4 protocol and receiver dongle (our recommended wireless solution for industrial users)
• DI-1000WiFi with wireless WiFi TCP/IP protocol
• DI-1000BLE with wireless BLE protocol

DI-1000U USB Sensor Cell Interface shown connected to a load cell, a torque sensor or a pressure sensor with mV/V output:

For dynamic measurements such as impact force measurement or for testing to failure you need very high speed data update rate to capture the data in a very short time span.

We offer three versions of the DI-1000U for that purpose:

16-bit USB Sensor Interfaces (DI-100U/DI-100UHS) and 24-bit USB Sensor Interfaces DI-1000U/DI-1000UHS/DI-1000UHS-1K/DI-1000U-5V work directly from the power supplied via the USB port. There is no need for additional external power supply. But if you are working with multiple USB load cells or interfaces, it is a good idea to use a powered USB Hub such as our HX-400 (Four channel hub) or HX-700 (Seven channel hub) in order to provide reliable power to all connected load cells.

For the wireless battery operated versions, we provide a power adapter to help you charge the internal rechargeable battery which can then be used to operate the sensor and interface not just wirelessly for the communication, but also cordlessly!

• The DI-1000U works with devices up to 2 to 25 mV/V with a variable gain setting and offers accuracies up to +/- 0.02% of full scale
• For high accuracy or for trade (NTEP) applications, the DI-1000U offers a superior high accuracy load cell and sensor interface
• XBee (802.15.4) Industrial Strength Wireless, WiFi or BLE Protocols
• Battery Operation with Rechargeable LiPo Battery included

We offer three different options for Wireless Sensor Interfaces:

For best results, Loadstar Sensors recommends using the DI-1000ZP for your wireless load cell communication needs. It has the best reliability and range of all available wireless solutions.

The DI-1000ZP wireless sensor interface comes with a separate USB receiver dongle that is attached to the PC's USB port in order to receive and read data from the DI-1000ZP via a Serial connection. This is the most robust and reliable connection especially in a industrial or factory setting. One can operate wirelessly up to 1000 ft from the transmitter built into ther DI-1000ZP. The max data rate though is only about 10 to 16 samples per second. So if you want fast and quick responses then we suggest you stick to the USB output and consider using a USB extender cable like our UX-100 or UX-300 devices as an add on.

The DI-1000WiFi transmits via WiFi and hence the PC or Tablet or Phone's built in WiFi receiver can be used directly to read and display values. When connected to a sensor such as a load cell, the wireless configuration would look like this:

If you wish to receive data on a WiFi connected PC, Tablet, Phone or other device, use the DI-1000U for USB access and the DI-1000WiFi for the easiest wireless access to the data. The DI-1000WiFi and DI-1000ZP offers a built-in cordless rechargeable battery operated wireless solution.We offer a free program on the Apple AppStore to display, log and plot data on an iOS device like an iPhone or iPad. The LoadVUE iOS App works in adhoc mode or in true wifi mode connecting to the device via a WiFi Router.

The DI-1000U-5V can be used as a general purpose USB Data Acquisition system for use with sensors that have a 0-5 V DC Output. Similarly if you wish to get wireless data transfer from your 0-5V sensors, then we offer three version with WiFi, BLE and 802.15.4 protocols for those sensors.

• Works with sensors that output a signal in the 0-5V DC range
• Examples of supported sensors include: LVDT (iLVDT) and String Potentiometer (iSP)
• Offerered with USB or Wireless (XBee, BLE or WiFi) output
• Offered in data update rates from 60 Hz to 1Khz

To start using one of these interface devices, simply connect the load cell to the terminal block on the interface device. Install the drivers provided on the software CD shipped with the product. Once installed, connect the USB connector to the PC via the USB port.

The load cell appears on the PC as a virtual COM port. Using a standard terminal emulator you can send commands to the sensor to display loads on screen. If you type the "?" command, you can see all the available commands on the device.

Before using the load cells to measure, you need to calibrate the interface device to work with YOUR load cell. If you purchased the interface device with a load cell from us, it will come pre-calibrated. If you bought it stand-alone, then either enter the calibration coefficient (typically 2 mV/V) into the interface device via ASCII commands or perform a two point calibration with a known weight. Once calibration is complete, you can view forces or weights in millipounds. Please refer to the manuals page for calibration quick start guides.

You can either display the data one at a time or display it in continuous operation mode. Alternatively, use our LoadVUE (for e.g. LV-1000) application to view/log/plot data on a PC.

If you wish to use this device with multiple resistive load cells - then we recommend that you use one Di-100/Di-1000 for each load cell or purchase a DI-400U Interface. Then you can calibrate each interface device to its connected load cell and then sum the four individual readings on a PC to get the total load. Using this approach - you will avoid the need to calibrate the entire system via a summing/junction box.
