Linear Potentiometer

Linear potentiometer are well known displacement transducers. The working principle is a voltage division on a hybride conductive film. It is possible to get different housing and mounting types, like versions for hydraulic cylinders with spherical, clamping jaw mounting or sprung loaded. The first linear potentiometer with a protection class of IP 68 and contactless measurement systems. The LMI- series constitutes a new generation of L. P. A ring magnet leads the transducer contactless in the inside of the sensor. Therefore a cyclenumber of over 100 Mio. is avieable without problems. Against traditional systems this series mutes additional vibrations over the contactless ring magnet. A well designed and inexpensive measurement system that will be established in the market very quickly.
