Vorrichtung zum Erfassen einer Dehnung und/oder einer Stauchung eines Koerpers

EP 964252 A UPAB: 20000323 NOVELTY - The deformed substrate (102) is applied to the body to record its stretch and/or compression. Switching elements of the evaluation device are arranged so that influences of stretching and/or compression on the function of the evaluation device are minimal. DETAILED DESCRIPTION - Apparatus for recording the stretching and/or compression of a wire strain gauge comprises: a deformable semiconductor substrate (102) on at least one element (R1, R2, R3) having a physical property that changes depending on the stretching and/or compression of the substrate (102); and an evaluation device (108, 112) arranged with the element on the substrate and connected to the element to produce a measuring signal depending on the stretching and/or compression. The evaluation device is arranged on the substrate so that it can be stretched and/or compressed. The deformed substrate (102) is applied to the body to record its stretch and/or compression. Switching elements of the evaluation device are arranged so that influences of stretching and/or compression on the function of the evaluation device are minimal. USE - Used for measurement transformers in power and torque moment sensors. ADVANTAGE - Temperature influences are compensated for
