发明名称 Method for measuring an acceleration using a piezoelectric vibrating accelerometer
摘要 The invention provides a method of measuring an acceleration by means of a vibrating accelerometer including a piezoelectric vibrating cell, the method having the steps: of exciting the vibration cell by means of an excitation signal at a resonant frequency of the vibrating cell; of calculating an acceleration value from a detection signal that results from the excitation signal; of exciting the vibrating cell with a correction excitation signal at a correction frequency that is different from the resonant frequency; of extracting a correction signal from the detection signal, the correction being representative of an electrical characteristic that is to be corrected; and of combining the correction signal with the detection signal so as to reduce the electrical characteristic that is to be corrected.
