Tips: How to choose the type of strain gauge?

The type of strain gauge is selected according to the purpose of strain measurement, the material of the test piece and its stress state as well as the requirements of measurement accuracy. For example, if the strain gauge is used as a sensitive element of a force measurement sensor at room temperature, the foil strain gauge with zero drift and minimal creep is used; if the output sensitivity of the sensor is required to be large, the semiconductor strain gauge is used; if it is used for dynamic strain measurement, the foil strain gauge is usually chosen.
