Webcircuit. Even if the Wheatstone bridge is initially balanced resistively so that R 1/R 4 = R 2/R 3, this will no longer be true, in general, when one or more of the strain gages in the bridge arms are strained. Consequently, the Wheatstone bridge is ordinarily operated in a resistively unbalanced state. In this mode of operation, resistance ... WebA simple and economical phase-sensitive detector circuit is described. The circuit, which was developed for use with large-area heat-flow sensors that employ resistance temperature detection, uses a synchronous rectifier driven by a square wave. It is shown that the circuit has good linearity, resolution, and immunity to external and internal ...

Wheatstone Bridge: Derivation, Formula & Applications
