Small-Transmitter (hol603)

Dich vụ sửa chữa, bảo dưỡng, cải tiến các hệ thống dây chuyền tự động công nghiệp

The ESW®-Small-Transmitter is used for permanent machine monitoring and can optimized for different application areas.
Measured value, signal assessment,frequency range,measurement range and output signal can be customized to the measuring task.
Unwanted vibrations,which occur through mechanical defects or imbalances, are detected at the monitored machines in time. Using the analog output,the following evaluation circuit or warning devices can be adressed. With 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®-Small-Transmitter, high reliability is guaranteed. 


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

  • Fan,pumps and air blower

  • shaker,decanter and separators

  • Conveying and transport equipment

  • Instrument, processing and production machines
