Semiconductor strain gauge bridge circuit

摘要

A semiconductor strain gauge bridge circuit device is disclosed to include a bridge circuit of semiconductor strain gauges, a first zero-point temperature compensation circuit connected to one of a pair of output terminals of the bridge circuit and including a voltage-dividing resistor circuit generating a voltage substantially equal to a potential appearing at the one output terminal at a predetermined temperature, and a second zero-point temperature compensation circuit connected to the other of the output terminals and including a resistive element having a temperature characteristic similar to that of the semiconductor strain gauges.
