Question

What is the disadvantage of the piezoelectric pressure sensor?

(a) It has too much sensitivity

(b) It can measure only low pressure

(c) It is not suitable for dynamic measurement

(d) It can only give pressure difference

I had been asked this question during an internship interview.

I'm obligated to ask this question of Engine Electronics topic in section Automotive Electronics, Engine Performance Parameter & Testing of Automobile Engines of Automobile Engineering

Answer 1

The correct answer is (d) It can only give pressure difference

Easiest explanation: The disadvantage of the piezoelectric pressure sensor is that it can only give the pressure difference. The advantages of the piezoelectric pressure sensor are quick frequency response and they are of small size.
