The article walks through how to make a measurement from bridge-based load cells, a step-by-step instructions for wiring and configuring your NI data acquisition device for strain gauge measurements. The principle also applies for bridge-based pressure and bridge-based torque sensors. The steps will be using an NI CompactDAQ system with an NI 9237 four-channel simultaneous bridge module and walk through setting up a Global Virtual Bridge Channel in NI Measurement and Automation Explorer (MAX) and testing the signal measurement and then where to find a LabVIEW example to start you application.
This article assumed basic knowledge of load cells, pressure, and torque transducer operating principles. Please review
