Semiconductor strain gauge uses _______(a) rectifier circuitry(b) power electronics circuitry(c) ordinary bridge circuit(d) bridge circuit with temperature compensationThe question was posed to me by my school teacher while I was bunking the class.The origin of the question is Strain Gauge Measurement Technique topic in section Transducers of Electrical Measurements

Answer»

Right option is (d) BRIDGE circuit with TEMPERATURE compensation

Explanation: The semiconductor strain gauge makes use of a WHEATSTONE practical bridge circuit along with temperature compensation. OUTPUT is MADE linear as the resistance characteristics with respect to strain are non-linear.
