If you need to do testing and data gathering or want to display values on a PC/Tablet via USB, simply connect the weigh module 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 weigh module 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.

If you do not need the very high precision of the DI-1000U, you can use our DI-100U digital load cell interface with 16 bit ADCs and Serial TTL or USB output.  The DI-100U is sufficient for accuracies of +/- 0.1% of full scale output.  Or in other words if you need to measure +/- 1 lb accuracy over 1000 lb range or +/- 0.1 lb accuracy over 100 lb range, then the DI-100U is more than adequate for your application. If you wish to connect a load cell with an Arduino or other microprocessors or microcontrollers, then you can disconnect the S2U Serial to USB converter adapter and directly communicate via UART. 

A lower priced version of the 4 sensor kit shown below with four individual DI-1000Us is available with a single integrated DI-400U 4 channel USB interface

You can use these weigh modules wirelessly by connecting it to our DI-1000ZP wireless load cell interface. This configuration allows you to wirelessly connect to a Windows/Unix/Mac computer. On a Windows platform, you can use our LV-1000 LoadVUE Pro software to display, log and plot force vs time data effortlessly. The DI-1000ZP uses the 802.15.4 protocol and offers robust connectivity to about 1000 feet in industrial environments. It comes with a battery backup for cordless operation for a couple of hours. If you wish to connect via WiFi or BLE we offer the DI-1000WiFi and DI-1000BLE that makes it easy to communicate with Smartphones as well.

Some users want a high level 0-5V analog DC output in order to work with existing data acquisition systems or PLCs. Ih that case, you can use this weigh module with our AI-1000 signal conditioner which provides an amplified 0.5 to 4.5V output proportional to the applied loads. We can provide the system together with calibration and the formula to convert from voltage to loads/forces when ordered in this configuration. We also offer the AI-1000-CV with 4-20 mA output if you prefer current output. Please contact us for this kit.
