DESCRIPTION:
The ESW® -Mini-C is used for permanent machine monitoring and corresponds at this technical execution to performance level PL-c.
Unwanted vibrations,which occur through mechanical defects or imbalances, are detected at the monitored machines in time. Using the alarm relay,warning devices can be adressed.Thanks to the early detection, a rising wear and the associated costs is avoided and the life time is prolonged. Also production losses are reduced,whereby a higher planning security is guranteed.
Through the integrated sensor, a stabil Die-cast aluminum housing and the easy installation and handling of the ESW® -Mini-C, high reliability is guaranteed. The device can be manufactured with an analog output, which behaves proportional to the measurement range.
