An LVDT is used to measure displacement. The LVDT feeds a Voltmeter of 0-5 V range through a 250 gain amplifier. For a displacement 0.5 mm the output of LVDT is 2 mV. The sensitivity of instrument is

0.1 V/mm

0.5 V/mm

1 V/mm

5 V/mm

Correct Answer: 1 V/mm

Explanation:

Final output = 2 x 10^-3 x 250 = 0.5 V.
