Abstract

A pressure transducer includes a sensor, a memory component, and a microprocessor. In one embodiment, a correction algorithm and set of compensation coefficients are provided and stored in the memory. The algorithm applies the compensation coefficients to determine a compensated pressure value. The pressure transducer may store the correction algorithm and the compensation coefficients for use in the field.
