A pressure transducer comprising a deflecting member fabricated from a semiconducting material having a first conductivity and a negative temperature coefficient of resistance, and four piezoresistive sensors fabricated from a semiconducting material having a second conductivity opposite to the first conductivity and a positive temperature coefficient of resistance, the sensors being disposed on a first surface of the deflecting member whereby the sensors are to be coupled to form a Wheatstone bridge configuration, and a temperature compensating resistor network fabricated from the semiconducting material of the first conductivity whereby when the resistor network is coupled to the sensors coupled in the Wheatstone bridge configuration, and a voltage placed across the bridge and the temperature compensating resistor network, an output is provided by the bridge which is independent of changes in temperature.
