(b) Capsule

(c) Diaphragm

(d) None of the mentioned

I got this question by my college professor while I was bunking the class.

The above asked question is from Measurement of Temperature in chapter Engine Electronics of IC Engine

Answer 1

The correct answer is:

(c) Diaphragm

A diaphragm is a sensing element consisting of a thin, flexible circular plate that can be actuated by a pressure differential applied across the plate. It is commonly used in pressure measurement devices like pressure sensors and gauges. When a pressure differential is applied, the diaphragm deforms, and this deformation can be measured to determine the pressure.
