Abstract: A new concept of theory and technique for Remote strain measurement with proper ambient temperature compensation has been presented here. This presented theory and technique not only produces dc output voltage, which is linearly proportional to the change in gauge resistance, but also it suppresses essentially all lead wire resistance effects with a shielded twisted pair cable.

Keywords: Remote strain measurement, Lead-wire compensation, Switching network, Sample and hold circuit
