Sensors of rotation are intended for monitoring of revolutions or speed. They are suitable especially in case of decentralized control. Inductive rotation sensors perform contactless monitoring of changes of revolutions compared with their reference value.  

A possibility to select reference revolutions is the extraordinary feature of the PSI RSx inductive rotation sensors.

Unlike the standard way of adjustment by potentiometer, adjustment of these sensors is based on principle of real measurement of reference revolutions. Increase or decrease of revolutions is signalized in regard to limit values of revolutions that are defined as a percentage of the measured reference revolutions change.

Table:

1. Automatically after stabilization of revolutions.
2. Manually by means of sensor input.
3. Value of reference revolutions will be lost after supply disconnection of the sensor.
4. Value of reference revolutions will remain preserved even after supply disconnection of the sensor.
5. Two limit values are available.
6. One limit value is available.
7. There is one output for each limit value.

• Signalizing of decrease or increase of revolutions.
• Delayed signalizing of revolutions decrease or increase after device activation. (It will prevent false signalizing during run-up of monitored device, until revolutions reach nominal value.)
• Signalizing of wear (small revolutions decrease) in advance of signalizing of failure (substantial revolutions decrease).
• Sensing of decrease of revolutions during the starting-up of the monitored device prior to the achievement of the nominal revolutions.

Sensors are available in sizes M18 and M30, built-in and non-build-in, version with cable or connector. The length of the case is 70 mm.
