Abstract

PURPOSE: To facilitate compensation of sensitivity temperature characteristics of semiconductor strain gauges and make possible the use of the strain gauges of much higher resistance values by forming a half bridge by using the semiconductor strain gauges.
CONSTITUTION: A band gap voltage generating circuit BVC which has a resistance voltage dividing circuit for setting the temperature coefficient of output voltage and a bridge circuit BC whose 2 sides are constituted by semiconductor strain gauges RG1, RG2 and which is driven by the output voltage of the circuit BVC are included and the output of the circuit BC is converted to a specified signal by a signal converting and amplifying part CONV using an operational amplifier. In this case, the circuit BC is constituted as a half bridge by RG1, RG2, constant current elements QG1, QG2 and resistances R5, R6.
