Vibration Monitoring for Cooling Towers

Vibration Monitoring for Cooling Towers

Article by CTC
Cooling towers are a logical choice for vibration monitoring. Due to their often critical role in maintaining operational efficiencies. We use vibration analysis to improve reliability and extend the lifetime of cooling tower equipment. 


How It Works

The machinery generally consists of three phases: motor, gearbox, and fan. Typically we install vibration sensors on the bearing surface in either the horizontal, vertical, or axial directions.

What We Offer

 

OPTION 1 : 4.0 Solution With Wi-care 200 

 

Using the Wi-care 200 hard- and software we can connect all types of sensors. These can vary from dynamic accelerometers to temperature-, pressure-, distance-, oil-, windspeed-,… sensors. In this way we can accurately predict failures using 4.0 algoritmes that combines all data.

OPTION 2 : Traditional Accelerometers 

 

Accelerometers:
5 sensors on both the motor and gearbox so 10 sensors in total.

General purpose sensors like CTC’s AC192 and AC194 series sensors rated at 100 mV/g can be recommended for applications over 30 CPM (0.5 Hz):

Low frequency applications from 6 CPM to 30 CPM (0.1 to 0.5 Hz) should use a 500 mV/g sensor like CTC’s AC133 or AC134 series accelerometers:

Cables and Connectors:

Using the correct cabling to take the signal to take the signal to a switch box located in a more easily accessible area is important.

CTC’s CB206 armored cables with several choices of connector are suggested for this purpose:

These cables can be connected to a switch box such as the SB262. This junction box is also capable of passing the signal through to a remote monitoring system such as a DCS, PLC, or SCADA System:
