What is a cooling tower vibration switch?

A vibration switch detects shock and vibrations inside your cooling tower and essentially shuts the tower down or sends out an alarm if they reach a pre-set level. This is probably the most inexpensive component you can make in your tower. The vibration switch is constantly monitoring the cooling tower to insure there are no excessive vibrations coming from it.

Cooling towers use fans that are installed at the top or bottom of the tower. These fans need to spin at an optimal rate to insure the cooling tower is doing its job and dissipating heat. As the fan spins, over time centrifugal force causes the fan to warp. Utilizing vibration switches can prevent this from happening.

Types of Cooling Tower Vibration Switches

Mechanical Vibration Switches

– These vibration switches require no power and rely on resistant forces that trigger a magnet that sets off an alarm or completely shuts the tower down.

Electrical Vibration Switches

– Electrical switches have no moving parts and can more accurately measure the vibrations in the cooling tower that completely shuts the tower down or sets off an alarm.
