Abstract
A pressure sensor and method wherein a resonant pressure transducer has a frequency F which changed depending on the applied pressure P and the temperature T. A temperature sensor measures the temperature T. A memory includes stored therein data points corresponding to the sensor's frequency F at difference applied pressures and temperatures. A processor is configured to generate several polynomials from the data points and calculate Pμ at Tμ when the transducer frequency is Fμ.
