The Velomitor CT Velocity Transducer is a low-frequency version of the standard Velomitor Piezo-velocity Sensor. It is specifically designed to measure casing vibration velocity on cooling tower and air-cooled heat exchanger fan assemblies that operate at or above 90 rpm (typically 100 to 300 rpm). The Velomitor CT Transducer is capable of measuring vibration amplitudes at these frequencies, as well as the vibration frequencies generated by the fan motor and speed reducer.

In addition, it is important to install the accelerometer transducer on the bearing housing or machine casing. Improper installation may reduce the transducer’s amplitude and frequency response, or generate false signals that do not accurately represent actual vibration. Refer to the appropriate instruction manuals and Application Notes for proper installation guidelines.

Upon request, Bently Nevada provides engineering services to identify the appropriate machine housing measurements and offer installation assistance if needed.
