Meggitt (Sensorex) (IS) SX36RV 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 determinate in factory, and the position

marked on both spindle and housing.

Applications

• Valve position measurement

• Steam turbine servo-valve

control

A rotary displacement sensor is free to make a full rotation, however, in practice, it is only

usually used up to ±45°, where the linearity is within 0.5% of full scale. This linearity

improves as the range decreases, typically 0.1% for a range of ±5°.

This series works with an AC/AC mode, and the signal can be treated with the Meggitt

(Sensorex) 690 210 266 signal conditioner.

The sensor is made from a light anodized alloy. Output is given through a 20 meter ETFE

isolated cable with gauge 26 copper wires.

They can be used :

- In surface industries

- In permanent presence of gaseous explosive atmosphere (zone 1) (for a zone 0

use ( * ), please consult us)

- With the gas listed in subdivisions MB, IIC

(*) the RVDT external housing includes aluminum; it shall be protected against any impact

or friction.
