    Tips: How to choose the resistance value of the strain gauge?

    The resistance value of the strain gauge is selected according to the requirements of the test instrument for the resistance value of the strain gauge and the sensitivity of the measurement strain, as well as the test conditions. For example, when doing stress testing, in order to match the resistance strain gauge, the 1200 strain gauge is generally used: for the sensor, in order to improve its stability or output sensitivity, high resistance (such as 3502, 502, 10002 or even higher) is often used. , sometimes considering the signal-to-noise ratio, the power consumption is also selected with a high resistance value strain gauge.
