Basic RVDT construction and operation is provided by rotating an iron-core bearing supported within a housed
stator assembly. The housing is passivated stainless steel. The stator consists of a primary excitation coil and
a pair of secondary output coils.
A xed alternating current excitation is applied to the primary stator coil that is electromagnetically coupled to
the secondary coils. This coupling is proportional to the angle of the input shaft. The output pair is structured
so that one coil is in-phase with the excitation coil, and the second is 180 degrees out-of-phase with the
excitation coil.
When the rotor is in a position that directs the available ux equally in both the in-phase and out-of-phase
coils, the output voltages cancel and result in a zero value signal. This is referred to as the electrical zero
position or E.Z. When the rotor shaft is displaced from E.Z., the resulting output signals have a magnitude
and phase relationship proportional to the direction of rotation.
Because RVDT’s perform essentially like a transformer, excitation voltages changes will cause directly
proportional changes to the output (transformation ratio). However, the voltage out to excitation voltage ratio
will remain constant. Since most RVDT signal conditioning systems measure signal as a function of the
transformation ratio (TR), excitation voltage drift beyond 7.5% typically has no effect on sensor accuracy and
strict voltage regulation is not typically necessary. Excitation frequency should be controlled within +/- 1% to
maintain accuracy.
