METHOD FOR PRESSURE MEASUREMENT AT CHANGING TEMPERATURES AND PRESSURE TRANSDUCER FOR PRESSURE MEASUREMENT AT CHANGING TEMPERATURES

A method for the compensating temperature gradient influences on a pressure measuring transducer, comprising the steps of: registering a pressure signal Sp(t); registering a temperature signal T(t); ascertaining a pressure measured value ps(Sp(t), T(t)); determining the time derivative of the temper...

Summary:A method for the compensating temperature gradient influences on a pressure measuring transducer, comprising the steps of: registering a pressure signal Sp(t); registering a temperature signal T(t); ascertaining a pressure measured value ps(Sp(t), T(t)); determining the time derivative of the temperature signal dT/dt; correcting the pressure measured value with a correction function, which depends on the time derivative, wherein, as a function of the sign of the time derivative, another correction function is selected, or other coefficients in a function of equal type are selected.
