Explosion-proof Electronic Vibration Switch DB-ZD-KF , monitor the machine vibration
Overview
Explosion-proof electronic vibration switch DB-ZD-KF is used for monitoring machine abnormal vibration
to be able to predict the machine breakdown. The electronic switch can monitor the machine vibration
status continuously, when vibration amplitude over the permissible value, the vibration switch will protect
the machine by output of the alarm signal or shutdown of the power supply.
The electronic vibration switch is suitable for various rotating machineries, such as motors, centrifuges
and blowers and pumps etc.
