A vibration switch is a tool that identifies the scope of the vibration to which it is exposed and gives some type of response when this scope exceeds a predetermined level.
The switch response is usually an electrical contact closure or contact opening. The electrical contact could be either solid-state device or an electro-mechanical relay.
Vibration Switch Working Principle
Vibration Switch is working in accordance with the pendulum switching principle.
How a Vibration Switch Works
A permanent swinging magnet holds a magnetic switch situated under a specific position. Because of the vibration, the magnetic field among Reed Switch and magnet variations.
Therefore, the switch gets actuated resulting in the suspension of the equipment. The responsive sensitivity of the device can be altered by adjusting the gap separating the switch and magnet. Consequently, vibrations with a scope below a set level can be suppressed.
The free pendulums length and the responsive frequency of the switch using a tone generator can be adjusted precisely to the natural frequency of the equipment to be safeguarded.
Why Use a Vibration Switch?
Vibration switches are mainly used for safeguarding vital machinery from expensive destructive failure by triggering an alarm or a complete shutdown when significant vibration of the machinery is identified.
On the other hand, a vibration switch can be used to alert when there is an lack of vibration, like when a motor stops functioning because of a slipped drive belt.
Applications include all kinds of spinning or reciprocating machinery like cooling tower fans, pumps, motors, etc.
