Acceleration measuring method, involves extracting correction signal representative of parasite electrical characteristic from detection signal, and combining correction signal with detection signal to reduce characteristic
The method involves exciting a piezo-electric vibrating cell (1) of a vibrating accelerometer using an excitation signal at a resonance frequency (f0) of the cell. An acceleration valve is calculated from a detection signal resulting from the excitation signal. The cell is excited with a correction excitation signal at correction frequencies (f1, f2). A correction signal representative of a parasite electrical characteristic to be corrected is extracted from the detection signal. The correction signal is combined with the detection signal using an adder (4) to reduce the characteristic. An independent claim is also included for a device for measuring acceleration using a vibrating accelerometer.
