The piezoelectric sensor operates by:
A)Altering the resistance values of the bridge circuit located on a ceramic disc.
B) Dropping voltage over a fixed resistor as pressure is applied to the switching transistor.
C)Generating a voltage within a thin ceramic disc voltage generator that is attached to a diaphragm that stresses the crystals in the disc.
D)None of these choices.

Question

Quizplus · Accepted Answer

Piezoelectric sensors generate a voltage within a thin ceramic disc voltage generator that is attached to a diaphragm that stresses the crystals in the disc. As pressure is applied to the disc, it generates a voltage that can be measured by external circuitry. Therefore, option C is the correct answer. Option A describes a different type of sensor, while option B is not a valid method for operating a piezoelectric sensor.
