Correcting differential pressure signals obtained from measuring transducer

摘要

The pressure measurement signal is measured and determined from first and second signals using a differential pressure transducer, and the temperature signal is measured in the differential pressure transducer. The coefficients (1,2,3,4) are determined, for each of the dependencies between the measured values to be corrected. The differential pressure signal recurring from the measured difference signal (11), the measured absolute pressure signal (12), the temperature signal (13) and itself, are corrected by logical linking with the correction polynomials, corresponding to their dependence.
