ABSTRACT:
A semiconductor-type pressure transducer is disclosed in which the pressure change is detected as a resistance change by use of a bridge circuit including at least a gauge resistor changing with an external force. Each gauge resistor is made of a PN junction of a semiconductor. The pressure transducer further comprises an amplification factor compensator for cancelling the effect of the temperature change of the gauge resistors making up the bridge circuit on the amplification factor of the amplification circuit for amplifying the output of the bridge circuit.
