Customers who bought this load cell also bought:

  • UX-100 USB extender cables for 15 additional feet from the DI-100U or DI-1000U USB load cell interface
  • Optional USB Relays that can be programmed to open or close based on force input from load cell to PC
  • Optional LoadVUE load cell software to display, log and plot the force data from USB load cells
 

The DI-400U Digital Load Cell Interface module provide a simple, convenient method to convert up to four millivolt output (mV/V) load cells into PC friendly USB Load Cells! Just plug in your strain gauge load cells into the connectors of our DI-400U and connect the USB port to a PC and you get a PC-ready solution. Using our LoadVUE LV-4000 software you can sum the loads as well as obtain individual loads from each load cell. Ideal for use with weight scales, balance platforms, Center of Gravity scales, etc. where the platform size is large and you need to read data from the four corners of the scale.

The max data rate from each channel is about 40 Hz from the base version and up to 240 Hz from the high speed upgraded version.  Note that in order to get 240 Hz from each of the channels, you will need to use it with our LV-4000HS high speed solution.

How it works

To start using this interface, simply connect your resistive load cells to the terminal blocks on the DI-400U load cell interface device.  Install the drivers provided on the software CD shipped with the product.  Once installed, connect the USB output connector to your PC or tablet.

The load cell appear on a PC as four virtual COM ports. 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-4000) application to view/log/plot data on a PC.
