DI-1000UHS-10K Load Cell Interface with USB Output
Highlights
The DI-1000UHS-10K High Speed Sensor Interface modules provides a simple, convenient method to amplify small signals like that from a load cell and then digitze the signal and apply calibrations to obtain calibrated force values through our LoadVUE Pro 10K software. You can Capture, Display, Log and Plot data on a PC using this software. Key Highlights of this device include:
- 16-bit resolution & provides accuracies to +/- 0.1% of full scale
- Configurable offset and gain setting for front end amplifier
- Works with most 4-wire load cells 0-4 mV/V load cells
- Has an external terminal block for easy connectivity with your sensor
- USB Digital Data access on a Windows 8/10/11 PC or Tablet
- One load cell or sensor connected to one DI-1000UHS-10K and calibrated together
- User selectable time span for test
- User selectable data rates (1 Khz, 5 KHz, 10 Khz...up to 50 khz)

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-1000UHS-10K Digital Load Cell Interface & use the USB connector on the DI-1000UHS-10K to connect to a PC via the USB port. The DI-1000UHS-10K is a signal conditioner & high speed digitizer and handles all the communications functions to talk with USB port of a PC. It needs to be used with the LoadVUE Pro 10K application software to display, log or plot data on a PC.

Importance of Data Capture Rate
When trying to capture the peak force during a test, the data capture rate is a very important consideration. If the duration of the peak is just a few milliseconds, then having a 1 Khz data capture rate means that you'll have just a few data points. In that case, one may miss the peak completely. And repeated tests may not give you satisfactory consistent results. That is why our faster solution with up to 50 khz data capture rate (of calibrated force values) maybe very important for your particular test.
LoadVUE Pro High Speed 10K Software
The LV-1000HS-10K software allows the user to "capture" the data during the test and then display the results on screen by opening the file. It cannot display the results in real-time unlike the LV-1000HS-1K software. For applications that need at least 10 data points in 1 millisecond, we recommend you select this higher speed 10 KHz version of the interface and software, which allows a user to capture data at up to 50 kHz.
Sometimes there might be multiple events during a test with its own local Peak/Low values that a user might be interested in. For such cases, we provide a special Region of Interest feature. You can set the time interval (beginning and ending times) on the plot that is of interest to you. The software calculates the Peak/Low/Delta between the two in THAT region.
Sample Data Files
Here are two sample data files (in CSV format) captured during a one foot drop test of a plastic object. The data was captured at 50 kHz. Each file has over 150,000 points. Since Microsoft Excel can graph only 32,000 points, you may need to use other software like R, Matlab etc to graph this data.
Our reasonably priced solution provides a very practical method of computing the actual measured forces as experienced by our sensor. The platform provided as part of our solution makes it easy for users to place test samples that will be subjected to the impact.
NOTE: You can use ANY of our resistive load cells and mate it with either the DI-1000UHS-1K (up to 1 KHz) or DI-1000UHS-10K (up to 50 KHz) high speed interface devices to create your own unique combination needed for your application. Just have to add SensorVUE software or LV-1000HS-10K software respectively to display, log and plot data on a Windows PC/Tablet.
If you are Ordering an Interface Only
The Interface needs to be mated and calibrated with the sensor. Once calibrated, these need to be used as a pair. You can not use the interface(s) interchangeably with other sensors.
If you are buying a new sensor with an interface, please add the appropriate Calibration Service for that sensor. For example, if you are buying a load cell then, add Compression, Tension, or Universal (both Compression and Tension) calibration, as needed for your application.
If you already have a sensor that you want to use with the new interface, you will need to send your sensor to us. Add the Calibration Service option to your order. We will calibrate the sensor with the new interface and send the calibrated pair back to you.
In case you would like to calibrate the sensor with the interface yourself, please ensure that you have the reference weights or reference equipment required for calibration and the calibration utility to compute and burn calibration coefficients. Our software LoadVUE Pro (LV-1000), SensorVUE (SV-1000), and ControlVUE (CV-1000) have the calibration utility built-in. Make sure you have the latest version of the software.

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