A strain gauge is a passive transducer that converts mechanical displacement into the change of resistance a strain gauge sensor is a thin wafer like device that can be attached to a variety of materials to measure applied strain. Strain gauge is a passive transducer that converts a mechanical elongation or displacement produced due to a force into its corresponding change in resistance r inductance l or capacitance c.

The strain gauge should be properly prepared by ideally gluing the strain gauge to the material being tested. Bonded metal foil strain gauge. The material construction of the wire directly affects the sensitivity of the strain gage. The resistance of a strain gauge should be high.

The percentage uncertainty in losses is 7 55 3 77 15 09 11 32 answerb a meter coil has a resistance of 100 ω and a full scale deflection current of 10 ma. The operation of the glue should isolate the wires from the material being tested. Some examples of primary sensors are a liquid in glass thermometer a thermocouple and a strain gauge. Strain gauges must have a good frequency response.

Applications are mainly static or quasi static strains. If a metal piece is subjected to a tensile stress the metal length will increase and thus will increase the electrical resistance. A strain gauge material should have low a. The power input and output in a device are 3650 w and 3385 w with each reading in doubt by 10 w.

The glue used should be specially prepared for use in the strain gauge. Bonding element in a strain gauge must have a zero insulation resistance b. Further discussion on sensitivity can be found in the strain gage sensitivity page. Measurements and instrumentation part two instructions.

Hi friends in this article i am going to describe you strain gauge working principle gauge factor and strain gauge load cell working. A strain gauge works properly only if the bonding material used is durable and keeps the gauge together to the surface of the material that is being tested. Here is complete set of 1000 multiple choice questions and answers. A strain gauge material should have low.

Its thickness should not exceed 10 micrometers. The strain gauge should have low resistance temperature coefficient. All of the above. View answer workspace report discuss in forum.
