To measure angular displacement by RVDT.

AIM:- to measure angular displacement by RVDT.

APPARATUS: - trainer kit, connecting leads.

THEORY: -
RVDT stands for rotary variable differential transformer .It same as LVDT expect that its core is cam shaped & may be rotated between the windings by a shaft.
                    At the null position of core output voltage of secondary windings S1 & S2 are equal and therefore net output is zero.
                   Any angular displacement from null position will result in a differential voltage output. Clockwise rotation produces an increasing voltage of a secondary winding of one phase while counter clockwise rotation produce an increasing voltage of opposite phase.

PROCEDURE:-
Connect the leads and switch on supply.
Give the angular displacement and read the output reading in voltage.

RESULT: -Thus we have measured the angular displacement using RVDT.
