ZK-B-11 Integrated Electronic Vibration Switch

ZK-B-11 Integrated Electronic Vibration Switch

Vibration monitoring is a means of early fault alarm for machines, as most auxiliary machine failures are reflected in the increase of vibration. The vibration switch can monitor abnormal vibrations of the machine and predict machine damage. It mainly monitors machine faults such as rotor imbalance, misalignment, bearing damage, and belt damage. This vibration switch can continuously monitor the vibration of the machine. If the vibration of the machine exceeds the allowable value, the vibration switch will provide an alarm or turn off the machine power, protecting the machine from damage. Suitable for various rotating machinery, such as motors, centrifuges, fans, water pumps, etc.

The vibration switch can work reliably under the following environmental conditions:

1. Altitude not exceeding 1000m;
2. Environmental temperature -30 ℃~+80 ℃;
3. The relative humidity of the surrounding environment is not greater than 80%;

The vibration switch will provide an alarm or turn off the machine power, protecting the machine from damage. Suitable for various rotating machinery, such as motors, centrifuges, fans, water pumps, etc.

• Vibration monitoring is an ideal early fault alarm method for machines, as most auxiliary machine failures are reflected in the increase of vibration. HZD-B-III electronic vibration switch monitors abnormal vibrations of the machine and predicts damage to the machine. HZD-B-III mainly monitors the following types of machine faults: rotor imbalance, misalignment, bearing damage, and belt damage.
• HZD-B-III Electronic Vibration Switch (Explosion proof)Can continuously monitor the vibration of the machine. If the vibration of the machine exceeds the allowable value, an alarm will be provided or the machine power will be turned off to protect the machine from damage. In most cases, vibration can indicate machine problems for a considerable period of time before the machine is damaged. For example, vibration monitoring can detect potential machine malfunctions much earlier than temperature monitoring.
