The Velomitor CT Velocity Transducer is a low-frequency version of the standard Velomitor Piezo-velocity Sensor. Its design is specifically intended to measure casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies that operate at or above 90 rpm (with 100 to 300 rpm being typical). 

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, be careful when installing the accelerometer transducer on the bearing housing or machine casing. Improper installation may decrease the transducer's amplitude and frequency response and/or generate false signals that do not represent actual vibration. Refer to the appropriate instruction manuals and Application Notes for proper installation guidelines. 

Upon request, Bently Nevada provides engineering services that can assist in identifying the appropriate machine housing measurements and offer installation assistance if needed.
