Patent abstract
A pressure sensor that has a sensor membrane for exposure to fluid at a pressure to be sensed, and a compensation membrane sealed from the fluid at the pressure to be sensed. Associated circuitry connected to the sensor membrane converts deflection into an output signal indicative of the fluid pressure. The circuitry also connects to the compensation membrane to convert deflection into an adjustment to the output signal that compensates for membrane deflection due to thermal expansion.
