Question

What is the name of an element which uses inductive coupling?

(a) Inducto conduct

(b) Inductosyn

(c) Conductosyn

(d) Conducto induct

This question was addressed to me at a job interview.

I need to ask this question from Coordinate Measuring Machines in portion Machine Tool Metrology of Engineering Metrology

Answer 1

Correct choice is (b) Inductosyn

To explain I would say: CMM utilize a measuring element known as Inductosyn data element. It uses inductive coupling between conductors and the conductors are separated by a small air gap. As Inductosyn is not subjected to wear, it does not develop inaccuracy.
