Measures bridge-based sensors, such as strain gages and load cells, in rugged environments. FieldDAQ™ devices are dust- and water-resistant and offer TSN technology for simplified distribution.

The Strain/Bridge Input Device for FieldDAQ measures up to eight channels and has built-in bridge completion and voltage excitation to support for quarter-, half-, and full-bridge sensors. The module also features anti-alias filtering, offset nulling, and shunt calibration to reduce the effect of noise and improve measurement accuracy. Additionally, the module incorporates time sensitive networking (TSN), which provides tight synchronization over a distributed network of data acquisition nodes without additional cabling or complex programming. The device features an integrated network switch and built-in power circuitry for simple daisy chaining.The Strain/Bridge Input Device for FieldDAQ Device includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
