PIEZOELECTRIC VIBRATION SENSOR

摘要

This piezoelectric vibration sensor is provided with a housing that houses a piezoelectric vibrator and a circuit board electrically connected to the piezoelectric vibrator. The piezoelectric vibration sensor is also provided with: a signal cable, which is inserted into the housing from a side plate of the housing, and is connected to the circuit board; and a deformation suppressing unit, which suppresses deformation of the circuit board when an external force is applied to the circuit board via the signal cable.
