Description：

The Velomitor CT Velocity Transducer is a low-frequencyversion of our standard Velomitor Piezo-velocity Sensor. ltsdesign specifically measures casing vibration velocity oncooling tower and air-cooled heat-exchanger fanassemblies that operate at or above 90 rpm (100 to 300 rpmtypical).

The Velomitor CT Transducer can measure vibrationamplitudes at these frequencies as well as the vibrationfrequencies generated by the fan motor and speed reducer.
