A device used for gauging the torque on an object by converting the strain applied as a mechanical motion into an electronic signal. Any change in Capacitance, inductance, or resistance is proportional to the strain.

What is the Difference between strain gauge and extensometer?
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
What are the output voltages of a strain gauge?
A strain gauge usually as a label on it indicating two things ,the range and so many mV/V output.If the range is 0 - 2 te and the mV/V is 1.5mV/V we then need to know the excitation voltage(V) of the instrument feeding the strain gauge.If the excitation voltage is 10 V then at the top end of the strain gauge (2te) the output of the strain gauge is 1.5mV X 10 =15mV.The mV output is indicated for it's range (2te) but is linear throughout the range therefor for half the range 1te the mV output is halved to 0.75 x 10 = 7.5mV.0te - 0mV0.5te - 3.75mV1te - 7.5mV1.5te - 11.25mV2te - 15mV
How do you set torque wrench at 62lbs?
Some have a setting screw, some have a pointer and gauge.
What is the difference between steric and torsional strain?
I think torsional strain happens only when two groups are eclipsed in relation to their positions to each other. This strain can be relieved by rotation about the carbon carbon bond. But steric strain can happen all the time. (when two groups are eclipsed, gauge or staggered in relation to each other.)
Factors affecting accuracy of strain gauges?
Temperature Variation - This can be one of the major causes of error in a strain gauge. It can easily change the gauge resistance and cause differential expansion between the gauge and the test piece, causing variation in the measurable strain.Humidity - Humidity can affect the accuracy by the breakdown of insulation between the gauge and the ground point. It also causes electro-chemical corrosion of gauge wire due to electrolysis.Small errors could be caused due to thermoelectric effect.The gauge will be erroneous even due to small factors like zero drift, hysteresis effect and so on.Magnetostrictive effect can also cause errors in strain gauges of ferromagnetic materials. It produces a small voltage fluctuation of almost 2 mill volts.

What would one use a strain gauge for?
Like the name suggests, a strain gauge is a device used to measure the strain of an object. The devices electrical resistance varies in proportion to the amount of strain on the device.
What is the purpose of a strain gauge?
A strain gauge is used to measure the strain of an object. It was invented by the inventors Edward Simmons and Arthur Ruge in 1938. There are several types of gauges (metallic, capacitance, photo-electrics and semiconductor gauges).
