Cooling Tower Monitoring

Cooling towers can be involved in accidents caused by broken blades or a broken gearbox.

Continuous monitoring of this type of machine is recommended. In fact, most cooling tower manufacturers install some type of machinery protection system in new installations.
In cooling towers, it is recommended to install vibration sensors on the gearbox to detect malfunctions in the air-cooling machinery and even shut down the machine when dangerous vibration levels are reached.
The vibration level can be monitored from the plant’s Distributed Control System via a 4–20 mA connection.
Furthermore, the vibration sensor mounted on the gearbox provides a dynamic signal from the key point to help the analyst diagnose the machine’s condition. This dynamic signal can be recorded using a vibration data logger for predictive maintenance and analyzed in predictive diagnostic software.
