Multiple choice

An LVDT produces an rms output voltage of 2.6 V for displacement of 0.4 micrometer. Calculate the sensitivity of the LVDT.

  1. 0.15 V/micrometer

  2. 5.6 V/micrometer

  3. 6.5 V/micrometer

  4. 1.54 V/micrometer

C Correct answer
Explanation

Sensitivity of LVDT (s) = (RMS value of output voltage) / (Displacement in micrometer) = 2.6/0.4 = 6.5 V/micrometer
