Abstract
PURPOSE: In a sensing system for vibration, pressure, etc. using piezoelectric sensors provided with a piezoelectric vibrator, the piezoelectric sensors are made one side of a four-side bridge, whereby the faults in the sensing system are accurately detected without increasing the number of wirings.
