CM-Series sets new standards for displacement measurement

The CM-Sensors are specially designed for demanding applications: They withstand high pressures up to 100 bars (and more) at temperatures up to 190 °C.  

The new ceramic minisensors can be used
without any mounting restrictions.

 At conventional sensors with a similar size the probe head must be kept free from surrounding conductive objects, in order to avoid pre-attenuation of the measuring system. In contrast, the socket for the CM-sensor does not require additional notches or holes.This feature arises from the utilization of zirconium oxide as housing material and ferritic components with a focusing effect. The CM-sensor is typically applied to monitor the orbit of a turbocharger’s shaft. Its ball bearings have a squeeze film damper to reduce the rotor vibration. In order to optimize the entire system the CM-sensors detect the exact position of the turbine- and compressor wheel under real operating conditions.
