CIPS – HUNGER Measurement System

CIPS (Ceraplate with integrated Positioning-System)

Hydraulic cylinders with CERAPLATE coating can be equipped with the incremental transducer system CIPS. Under the coating on the piston rod grooves are placed , which width and spacing represent the scale.

One sensor with two integrated sensor elements (displace by 90 °) detect the direction of the movement and count the grooves under the coating. The sensor elements are working according to the Hall-effect and are providing rectangular output signals, which are processed by the consecutive electronic. A Phase discriminator is quadrupleing the pulses and thereby providing a four times higher density in comparison to the width of the grooves on the piston rod.

Application example

The sensor is fitted in a ring and protected by a stainless steel housing. By two guiding elements as well as by a mechanical spring a constant gap between the sensor haed and the rod surface is guaranteed.
The sensor housing is sealed again the oil chamber and the environment.
Sensor wiring is protected by stainless steel tubes.
The electric connection is carried out in a sealed clamp box (IP 68).
