Vibration sensor LS

The LS 100 and LS 200 sensors are used to detect absolute vibrations on machines in the frequency range 10 to 1000 Hz in applications up to max. 200°C. The sensors work according to the electrodynamic/inductive principle and supply a voltage signal proportional to the vibration velocity via a coil. Versions for horizontal or vertical installation are available.

The robust stainless steel housing, as well as the shielded cable in a stainless steel protective tube, make the sensor particularly resistant to harsh mechanical and aggressive industrial environments. The sensor is therefore particularly suitable for continuous condition monitoring of machines.

In conjunction with an electronic evaluation unit, the sensor is suitable for the
continuous monitoring of machines / condition monitoring in accordance with VDI 2056 and DIN/ISO 3945.
