Disclosed is a system wherein the compensation for temperature effects on a pressure measurement gauge are accomplished by processing the raw pressure measurement signal from the gauge through an equation to produce a thermally compensated measurement. The equation expresses the thermally compensated pressure determination as a relation between a derivative of temperature and temperature. When the gauge is placed in an oil or gas well, the equation is used to obtain the corrected measured pressure from the raw measured pressure received from the gauge and the temperature measured adjacent to the gauge.
