Abstract
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 a correction for the measured pressure from the temperature measured adjacent to the pressure gauge.
