Electronic Measurements And Instrumentation

  1. An LVDT is used to measure displacement. The output of the LVDT is connected to a voltmeter of range 0 to 5V through an amplifier having a gain of 250. For a displacement of 0·5 mm, the output of the LVDT is 2 mV. The sensitivity of the instrument would be:
    1. 0·1 V/mm
    2. 0·5 V/mm
    3. 1 V/mm
    4. 5 V/mm
Correct Option: C

Sensitivity of LVDT =
output voltage
displacement

=
2mV
0·5mm

= 1V/mm.
