Strain gauge is used to convert mechanical displacement into change in resistance
Answers
A Strain Gauge is an instrument used to measure strain on an object. It converts pressure, force, weight, tension etc. to electrical resistance, which can then be measured. Strain Gauge contains a sensor which converts physical forces into electrical resistance.
Strain Gauge was invented by Edward E. Simmons and Arthur C. Ruge, in 1938.
Strain Gauges are used mainly for measuring torque in energy systems, electric vehicles etc.
Answer:
TRUE
Explanation:
Strain gauge is used to convert mechanical displacement into change in resistance - TRUE
To measure the strain, strain gauge is used. It is a passive transducer. In strain gauge transducer mechanical displacement or elongation is produced a result to a force is converted into corresponding change in inductance, resistance or capacitance .
. If a metal is subjected to a stress (tensile stress), then the metal length will increase. This will increase the electrical resistance of the material. Similarly, if the metal is exposed to compressive stress, the length will decrease, however the breadth will increase. This will change the electrical resistance of the conductor.
