RVDT is used to measure: Correct Answer angular displacement

RVDT:

  • RVDT stands for “Rotary variable differential transformer”.
  • It measures angular displacement i.e. its output is an AC current that is linearly proportional to the angular displacement.

The basic circuit diagram for an RVDT is as shown:

Note:

LVDT

  • LVDT stands for Linear variable differential transformer.
  • It measures linear displacement since its output is AC-current which is linearly proportional to linear displacement.
