Vibration Monitoring


The ESW®-Mini is used for permanent machine monitoring.

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, high reliability is guaranteed. The device can be manufactured with an analog output, which behaves proportional to the measurement range.

Application fields: 


At all technical applications in which oscillations occur, the ESW®-Mini is a valuable support. Here are some examples:


  • Fan,pumps and air blower
  • shaker,decanter and separators
  • Conveying and transport equipment
  • Drives
  • Instrument, processing and production machines
