Question

Pair the quantities (p) to (s) with the measuring devices (i) to (iv).

• A. (i) - (r), (ii) - (s), (iii) - (q), (iv) - (p)
• B. (i) - (p), (ii) - (s), (iii) - (r), (iv) - (q)
• C. (i) - (r), (ii) - (s), (iii) - (p), (iv) - (q)
• D. (i) - (q), (ii) - (s), (iii) - (p), (iv) - (r)

Hint:

Remember: LVDT → displacement, Thermistor → temperature, Strain gauge → torque/strain, Diaphragm → pressure.

Answer 1

The Correct Option is C

Step 1: Recall measurement principles.
- (i) LVDT → measures linear displacement/position → (r).
- (ii) Thermistor → resistance varies with temperature → (s).
- (iii) Strain gauge → detects strain; can be used in torque measurement → (p).
- (iv) Diaphragm → measures differential pressure → (q).
Step 2: Verify mapping.
Thus, the correct matching is (i)-(r), (ii)-(s), (iii)-(p), (iv)-(q), which corresponds to option (C).
