Small-Compact/Ex (hol660)

Vibration Monitoring

The ESW® - Small-Compact / Ex (hol660) used for permanent machine monitoring.
Undesired vibrations that occur owing to mechanical defects or imbalances in the machine being monitored are detected early. With the help of the two alarm relay warning devices can be addressed. Thanks to this early detection, increased wear is avoided with the associated costs and extend the life. Production downtimes are reduced, resulting in a higher planning security is guaranteed.
The integrated sensor, the high-quality housing and simple installation and operation of the ESW® - Small-Compact / Ex (hol660) high reliability is ensured.
Other features include the adjustable measurement range, the switchable analog output, which can be used to set the alarm limits, and the self-test function.
Optionally can be activated for one of the two relay alarm memory.
The device is approved under atmospheric conditions or flammable dusts for use in gas-air mixtures according to the ATEX Directive 94/9 EC.
Labeling gases: II 2G Ex d IIC T6 Gb /
Labeling dusts: II2D Ex tb IIIC T80°C Db
Also an IEC Ex Declaration of Conformity is available: IECEx BVS 13.0006X
