  • Method for correcting pressure measurement for the influence of temperature in a sapphire gauge
    Patent number: 7100450
    Abstract: The invention concerns a method for correction with temperature in the pressure determination of a pressure gauge, comprising: measuring simultaneously with said gauge said pressure Pm(t) and said temperature Tm(t) during time, generating a signal Tf(t) of said measured temperature Tm(t), said measured temperature being filtered of the noise, (19) correcting said measured pressure Pm(t) with a correction function F(t) containing exclusively a dynamic part, said dynamic part containing a term a1 proportional to first derivative of said Tf(t) signal relative to time. In another aspect of the invention the dynamic part further comprises a second additional term a2 proportional to second derivative of said Tf(t) signal relative to time.
