Question

LVDT is used to measure ______________

(a) crank angle

(b) engine speed

(c) large displacements

(d) gas temperature

This question was posed to me in examination.

My enquiry is from Engine Management Systems topic in section Engine Electronics of IC Engine

Answer 1

The correct answer is:

(c) Large displacements

LVDT (Linear Variable Differential Transformer) is used to measure large displacements with high accuracy. It works by converting linear displacement into an electrical signal, commonly used in engine systems to measure piston movement, valve position, or other mechanical displacements.
