Patent ID: 7100450

Claim:
A method for correction with temperature in the pressure determination of a pressure gauge, comprising: measuring simultaneously with said gauge said pressure P m (t) and said temperature T m (t) during time, generating a signal T f (t) of said measured temperature T m (t), said measured temperature being filtered of the noise, correcting said measured pressure P m (t) with a correction function F(t) containing exclusively a dynamic part, said dynamic part comprising: a term a 1 proportional to first derivative of said T f (t) signal relative to time; a second addditional term a 2 proportional to second derivative of said T f (t) signal relative to time; and wherein the term a 1 is determined for a specific population of said pressure gauge, before the step of measuring simultaneously with said gauge said pressure P m (t) and said temperature T m (t).
