About the SX36RV120 RVDT

The SX36RV120 provides a sinusoidal signal, with a linear voltage over the measurement range.

The primary is excited by an AC voltage, and is picked up by the secondary winding on the transformer principle; the position of the rotating core determines the transformer ratio of each secondary winding.

As the secondaries are wound in opposition, the difference between the secondary outputs is proportional to the core angle, relative to the housing.

The zero position is where each secondary voltage is equal and opposite. This is determinated in factory, and the position marked on both spindle and housing.

The sensor is made from a light anodised alloy. Output is given through a 20 meter ETFE isolated cable with gauge 26 copper wires.
