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

摘要

The invention relates to a method for compensating for temperature gradient influences on a pressure transducer, comprising: registering a pressure signal S_p(t), registering a temperature signal T(t), determining a pressure measurement value p_s(S_p(t), T(t)), determining the temporal derivation of the temperature signal dT/dt, correcting the pressure measurement value with a correction function that depends on the temporal derivation, characterized in that a different correction function is selected or different coefficients are selected in a function of the same type depending on the algebraic sign of the temporal derivation.
