The Velomitor CT Velocity Transducer is a low-frequency

version of our standard Velomitor Piezo-velocity Sensor.  Its

design specifically measures casing vibration velocity on

cooling tower and air-cooled heat-exchanger fan assemblies

that operate at or above 90 rpm (100 to 300 rpm typical).

The Velomitor CT Transducer can measure vibration

amplitudes at these frequencies as well as the vibration

frequencies generated by the fan motor and speed reducer.
