DI-1000U Load Cell Interface with USB Output

This interface is similar to our DI-100U load cell interface, but offers much greater resolution and accuracy to support your most demanding application. The 24-bit ADC of this load cell digital signal conditioner, provides enough accuracy to support accuracy demanded by NTEP standards and it support both 4 wire and 6 wire resisitve bridge type load cells made from strain gauges. The load cells are powered by USB and communicate via ASCII command set over USB. The DI-1000 series supports data rates up to 1 KHz and offers both USB and Wireless communications options.

Highlights

The DI-1000U Digital Load Cell Interface modules provide a simple, convenient method to convert existing milli-volt (mV/V) output load cells into PC, Mac and Linux friendly USB Load Cells. Display, log and plot data on a PC using LoadVUE Pro, SensorVUE or ControlVUE software. Or connect the load cells digitally with a Raspberry Pi via USB and communicate via ASCII Commands. Key highlights of the DI-1000U are:

  • 24-bit resolution & provides accuracies to +/- 0.02% of full scale
  • Configurable gain to optimize resolution for full span of signal (-2V to +2V)
  • Works with most 4-wire and 6-wire load cells 0-4 mV/V load cells
  • Has an external terminal block for easy connectivity with your sensor
  • Appears as a Virtual COM port on a Windows PC, Mac or Linux machines
  • ASCII command set to allow users to write their own software applications
  • One load cell or sensor connected to one DI-1000 and calibrated together
  • Works with LoadVUE, SensorVUE or ControlVUE software to display, log or plot data
  • Write your own code using the built in API with simple ASCII command sets
  • Optional data update rates up to 500 Hz (DI-1000UHS) or 1 KHz (DI-1000UHS-1K)
  • Optional wireless functionality with XBee, WiFi or BLE output
DI-1000U-5V and DI-1000UHS-5V and DI-1000UHS-1K-5V supports a 0-5 V DC device like an LVDT or String Pot Displacement sensor.

DI-1000U with USB Load Cell Configurations

If you need to do testing and data gathering or want to display values on a PC/Tablet via USB, simply connect the load cell to the DI-1000U Digital Load Cell Interface & use the USB connector on the DI-1000 to connect to a PC via the USB port. The DI-1000U is a signal conditioner & 24-bit digitizer (good enough to handle load cells with 0.02% of full scale accuracy) and handles all the communications functions to talk with USB port of a PC.  When connected this way, 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. They can be displayed either one reading at a time or in continuous operation mode. You can also use Matlab, LabView or other popular programs to communicate and get calibrated readings from the load cell. It would be best if used our LoadVUE Pro application to display, log or plot data on a PC.

FAQ

What is the accuracy offered by the DI-1000U?

The DI-100U has a 24 bit ADC and supports devices with at least +/- 0.02% accuracy of full scale

What are the inputs/outputs from the DI-1000U?

The DI-1000U and DI-1000UHS and Di-1000UHS-1K can connect with four wire or six wire resistive load cells (mV/V) made using strain gauges in bridge configurations (half bridge, full bridge). The base outout is USB and the unit comes with a on/off switch and a six foot miniB to USBA cable.

How many load cells can it work with?

The DI-1000U can only be connected with one load cell at a time. You MUST mate the DI-1000U with a load cell and calibrate it before using it. The calibration is stored in the DI-10090U. So the load cell and DI-1000U or DI-1000UHS or DI-1000UHS-1K must be used together as a pair. If you want to use it with another load cell then you MUST recalibrate the new pair prior to use.

Does it need a power supply?

No. The DI-1000U is powered by USB and communicates via the USB port of a PC or Raspberry Pi. Only when using the wireless version of the DI-1000, does one need the external power supply provided with the unit when you purchase a wireless unit.

Differences between DI-1000U/DI-1000UHS/DI-1000UHS-1K?

The only difference between the three versions is that the max data outpur rate from the DI-1000UHS is about 500 Hz and the DI-1000UHS-1K is 1 khz vs. the 60-80 Hz from the DI-1000U. The DI-1000UHS and DI-1000US-1K operates at 203400 baud rate vs the 9600 baud rate of the DI-1000U. All of them can be used with the LV-1000 LoadVUE Pro software to display, log and plot data on a PC.

Differences between DI-100U/DI-400U/DI-1000U

The DI-100U/DI-100UHS/Di-400U/DI-400UHS devices have a 16 bit ADC built in vs. the 24 bit ADC of the DI-1000U/DI-1000UHS/DI-1000UHS-1K devices. The DI-100U/DI-400U family works ONLY with 4-wire load cells. The DI-1000U family works with 4 or 6 wire load cells. The DI-100U family can connect with an Arduino via UART/Serial TTL pins whereas the DI-400U and the DI-1000U only offers USB output. The DI-100U/DI-100UHS devices need the S2U serial to USB dongle to connect via USB to a PC or Raspberry Pi. The DI-400U/DI-1000U connect directly via a miniB to USB A USB cable with a PC or Raspberry Pi but cannot connect to an Arduino since no UART pins are accessible. For accuracies of the order of +/- 0.02% or better (NTEP level accuracies) use the DI-1000 family. For moderate accuracy, low cost applications, use the DI-100U if you need just one channel otherwise for up to four channels, use the DI-400U.

Can one DI-1000U be used with multiple load cells?

A load cell is an analog low level device. It must be mated with a DI-1000U or its variant and calibrated together. The calibration coefficients are stored in the DI-1000U or its variant. That is why you cannot simply switch load cells and use it with the DI-1000U. You must calibrate a load cell with the DI-1000U before use and label it properly to identify the pair. Best to keep the pair together and use them as a pair. If you must switch load cells then you MUST recalibrate the new pair prior to use.

Do you offer a 4 Channel version of the DI-1000U?

At present we only offer a single channel version of the 24 bit load cell signal conditioner. So you must use for DI-1000U units if you want to work with four load cells. Or use a junction box and then input that into the DI-1000U. We do offer a 16 bit four channel USB load cell solution - the DI-400U. Check that out to see if it meets your needs.

Can you connect the DI-1000U to an LCD Display?

Yes. You can connect a calibrated load cell + DI-1000U or DI-1000UHS pair to a DS-3000-Pro single channel or four channel display to view the output on a dedicated LCD Display.

Do you offer calibration service?

Yes. We offer calibration service on new sensor purchases as well as recalibration service for previously purchased sensors. We use NIST traceable reference standards to perform and validate the calibration and provide a free calibration certificate as part of the service. We are NOT ISO certified.

How can I get pricing information?

You can register on our website, login and see all prices, download spec sheets and solid models. You can also send us an email with your contact information and shipping address and we will be happy to send you a formal quote.

What is your return policy?

We give you a 30 day guiarantee for you purchase. You can exchange or return your purchased products for a refund of the purchase price of the product. Any calibration service fees, shipping and payment fees cannot be refunded. Feel free to try out our products risk free and see for yourself how easy we make it for you!

What is the typical lead time?

We need between one and two weeks usually to ship your order for items in stock. This is because we have to make your sensor, interface and calibrate them together, make sure the quality meets all specs and then pack and ship it to you. We offer expedited processing options if you are in a rush and need to get sensors sooner. If out of stock or if sensors are needed in volume, we could take 4-6 weeks or longer. Please contact us to get an estimate of price and lead time for your particular needs.

Do you offer educational discount?

We believe teaching young kids and encouraging R&D is crucial to make this world a better place. We support teaching and research activities in educational institutions with a 10% education discount on purchased products in exchange for sharing write ups, pictures, video clips and other material we can use in our marketing materials on and off line.
