DI-400U Four Channel Load Cell Interface with USB Output

Thie DI-400U USB Load Cell Interface 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 one to a port and then obtain calibrated force/load/weight values from all four connected load cells via a single USB output.

By using this device, you can save time, money and a lot of 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!

This device offers the easiest way to build a scale with four independent measurements at the four corners of a frame/platform. 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.

DI-400U Setup and Calibration

Calibrating Load Cells with DI-400U

FAQ

What is the accuracy offered by the DI-400U?

The DI-400U has four 16 bit ADCs - one per port - and offers at least +/- 0.1% accuracy of full scale

What are the inputs/outputs from the DI-400U?

The DI-400U and DI-400UHS can connect with up to four 4-wire resistive load cells (mV/V) made using strain gauges in bridge configurations (half bridge, full bridge). The base outout is one single USB output with a USB A connector. The unit is powered by USB. Each load cell shows up as a virtual COM port on a PC. So you get four individually addressable ports. You can use SensorVUE or ControlVUE software on a WIndows 8/10 PC to display, log and plot data.

How many load cells can it work with?

The DI-400U can be connected with up to four load cells simultaneously. You MUST mate the DI-400U with the load cells and calibrate each one before using it. The calibration is stored in the DI-400U one per port. The load cells and DI-400U or DI-400UHS must be used together as a set. 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-400U is powered by USB and communicates via the USB port of a PC or Raspberry Pi. No external power supply needed.

How is the DI-400U different from DI-400UHS?

The only difference between the two is that the max data output rate from the DI-400UHS is about 250 Hz per port vs. the 40 Hz from the DI-400U. The DI-400UHS operates at 203400 baud rate vs the 9600 baud rate of the DI-400U. Both can be used with the SensorVUE software to display, log and plot data on a PC.

Comparison between the DI-100U/DI-400U/DI-1000U interfaces?

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 you connect the DI-400U to an LCD Display?

Yes. You can connect the calibrated load cells + DI-400U set to a DS-3000-Pro four channel display to view the output on a dedicated LCD Display. The USB output from the DI-400U will be connected to the USB input of the DS-3000-Pro-4 and powered by the USB port. No external power needed.

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.
