Question

The output of a LVDT is connected to a 4 V voltmeter through an amplifier whose amplification factor is 500. An output of 1.8mV appears across the terminals of LVDT when the core moves through a distance of 0.6mm. If the milli-voltmeter scale has 100 divisions and the scale can be read to 1⁄4 of a division, calculate: [4 Marks] I) the sensitivity of LVDT II) The resolution of the instrument in mm.

Answer 1

Answer:

Explanation:

Now sensitivity LVDT = 4mvmm

Now whose sensitivity = 250 * 4mvmm

=1vmm

The resolusion of whose setup = 1/5 * (0.05)

=0.01v

Now Resolution in mm is 0.01 mm.
