Question

The output of an LVDT is ±2 mV when core moves through a distance of 0.5 mm. The sensitivity is:

• A. 0.25 mm/mV
• B. 4 mV/mm
• C. 0.25 mm/V
• D. 4 mm/V

Hint:

Sensitivity = Output / Displacement. Use consistent units (e.g., mV and mm).

Answer 1

The Correct Option is B

Sensitivity = \[ \frac{\text{Output Voltage}}{\text{Displacement}} = \frac{2 \text{ mV}}{0.5 \text{ mm}} = 4 \text{ mV/mm} \]
