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).
