Question

Some of the examples of non-contact sensors includes _______ .
(A) Proximity sensors
(B) Temperature sensors
(C) Torque sensors
(D) Acoustic sensors
Choose the correct answer from the options given below:

• A. (A), (B)and(D)only.
• B. (A), (B)and(C)only.
• C. (A), (B), (C)and(D).
• D. (B), (C)and(D)only.

Hint:

Non-contact sensors are commonly used in applications where direct contact might damage the object or when measuring delicate or inaccessible objects

Answer 1

The Correct Option is A

Non-contact sensors are those that do not require physical contact with the object to measure its properties Proximity sensors temperature sensors and acoustic sensors are examples of non-contact sensors Torque sensors however require direct contact with the object being measured
