These are non-inductive strain gauges suited to the measurement in magnetic field. The sensing element of the gauge consists of two identical grids with one grid folded back on another. This construction makes to cancel the electromagnetic noise induced in the grids. The twisted leadwire of the gauge is also effective to cancel the noise induced in the leadwire in the same way. Accordingly, this strain gauge is less sensitive to the influence of noise induced in changing magnetic field. It utilizes polyimide resin for the backing and is applicable to the measurement in high temperature.
