A strain gauge material should have low mcq.
The resistance of a strain gauge should be high.
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.
If a metal piece is subjected to a tensile stress the metal length will increase and thus will increase the electrical resistance.
It should possess linear characteristics in order to have the constancy of calibration over its entire range.

A strain gauge is basically used to measure the strain in a work piece.
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.
Further discussion on sensitivity can be found in the strain gage sensitivity page.
Some examples of primary sensors are a liquid in glass thermometer a thermocouple and a strain gauge.
The linearity should be maintained within accuracy limits.
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.
Bonded metal foil strain gauge.
The strain gauge should have low resistance temperature coefficient.
The strain gauge should be properly prepared by ideally gluing the strain gauge to the material being tested.
In the case of the mercury in glass thermometer the output reading is given in terms of the level of the mercury and so this particular primary sensor is also a complete measurement system in itself.
