DYNAMIC PRESSURE CORRECTING DEVICE OF PIEZOELECTRIC PRESSURE SENSOR AND CORRECTING METHOD THEREOF

摘要

PURPOSE: A dynamic pressure correcting device of piezoelectric pressure sensor and correcting method thereof is provided to enhance the accuracy of the system by minimizing the correcting error. CONSTITUTION: The present invention discloses a dynamic pressure correcting device of piezoelectric pressure sensor comprising:a low pressure correcting unit(10); an interface card(20); a controller(30); a general purpose interface bus(40); a signal acquiring unit(50); and a voltage correcting unit(60). Further, the present invention discloses the correcting method of the dynamic pressure correcting device comprising:an initializing step(S1) initializing variables and correcting a hardware; the first correcting step(S2) generating standard pressure to correct a reference pressure sensor; and the second correcting step(S3) applying standard correcting pressure to a corrected sensor and simultaneously receiving and processing signal generated from the sensor.
