  • Wheatstone Bridge Circuit and Theory of Operation

    2020-9-22 · A Wheatstone bridge uses two balanced legs in a bridge circuit to measure the unknown resistance of one resistor in one of the four legs. If this unknown resistance is a device such as an RTD, we can make an extremely accurate measurement of the resistance of that device.

    The Wheatstone bridge has a single impedance-variable element that is inherently nonlinear away from the balance point. Bridge circuits are commonly used to detect the temperature of a boiler, chamber or a process situated perhaps hundreds of feet away from the actual circuit.Usually a sensor element--typically a resistance temperature detector (RTD), a thermistor or a thermocouple--is ...

    Thermal Conductivity Detector (TCD) A TCD is using a Wheatstone bridge (see schematic below). The reference cell is filled with the carrier gas only, the sample cell will see a change when the combustion takes place and the measured gas is carried and introduced in it. TCD has no selectivity – only a change in resistivity is measured.
