Abstract

Για τη διόρθωση των παραποιημένων τιμών μέτρησης σε διηθητική μέτρηση της πίεσης οδηγείται η μετρούμενη πίεση διαμέσου του γεμάτου υγρό συστήματος (1, 2) σε έναν εξωτερικό μετατροπέα (3) της πίεσης. Το ηλεκτρικό σήμα εξόδου του μετατροπέα της πίεσης προσάγεται σε έναν αναλογικό ψηφιακό μετατροπέα (4) μίας μονάδας επεξεργασίας σήματος (5) για την ψηφιακή ανάλυση Φουριέ. Στη συνέχεια εκτελείται η κατά τον τρόπο του κτύπου ανάλυση και το σήμα συνδέεται στη βασική θέση της ανάλυσης με εμπειρικά εξακριβωμένα δεδομένα διόρθωσης. Τα δεδομένα διόρθωσης αποδίδονται σαν συντελεστές Φουριέ και από τη μονάδα επεξεργασίας του σήματος (5) το διορθωμένο σήμα οδηγείται σε μία μονάδα εξόδου και / ή αξιολόγησης (6).To correct false measured values in filter pressure measurement, the measured pressure is fed through the liquid-filled system (1, 2) to an external pressure transducer (3). The electrical output signal of the pressure transducer is fed to an analog-to-digital converter (4) of a signal processing unit (5) for digital Fourier analysis. Beat-wise analysis is then performed and the signal is connected to the analysis baseline with empirically verified correction data. The correction data are rendered as Fourier coefficients and from the signal processing unit (5) the corrected signal is fed to an output and/or evaluation unit (6).
