Jiangyin Zhonghe | DB-ZD-KF Explosion-Proof Electronic Vibration Switch (Centrifuge Vibration Protection Device) has Explosion-Proof Certificate

Overview:

DB-ZD-KF explosion-proof electronic vibration switch (centrifuge vibration protection device) has an explosion-proof certificate and can monitor abnormal vibration of the machine and predict damage to the machine. The electronic vibration switch can continuously monitor the vibration of the machine. When the vibration of the machine exceeds the allowable value, the vibration switch will provide an alarm signal or shut down the power supply of the machine to protect the machine. The electronic vibration switch is suitable for various rotating machines, such as motors, centrifuges, fans, water pumps, etc.
