AC Pick-Offs

These devices give an AC output signal, the magnitude of which varies with the angle of rotation over a maximum range of ± 45 degree. Both input and output windings are wound on the stator, with each being a single phase.

AC pick-offs are used where ratio-metric signal conditioning is not required but where weight reduction and general simplicity are paramount requirements.

For devices capable of providing more accurate data over a wider angular range, please refer to our range of rotational variable differential transformers (RVDTs) and Resolvers.

The pick-offs shown here are used to monitor a gas turbine inlet guide vane and as part of the seeker head gimbal for an anti-tank missile.
