Zhuang Diao PLC
Product Features:
1.Sensitivity:
3.94mV/mm/s (100 mV/in/s) ±5%.
2.Frequency range:
Frequency range adjusted downward to 3.0 Hz to 900 Hz ±1.0 dB or 1.5 Hz to 1.0 kHz ±3.0 dB to enable velocity sensor to measure vibration for fans running as low as 90 rpm.
3.Cabling:
Up to a maximum cable length of 305 m (1,000 ft).
The Velomitor CT Velocity Transducer is a low-frequencyversion of our standard Velomitor Piezo-velocity Sensor. Itsdesign specifically measures casing vibration velocity oncooling tower and air-cooled heat-exchanger fan assembliesthat operate at or above 90 rpm (100 to 300 rpm typical).
The Velomitor CT Transducer can measure vibrationamplitudes at these frequencies as well as the vibrationfrequencies generated by the fan motor and speed reducer.

Most common machine malfunctions (unbalance,misalignment, etc.) occur on the rotor andoriginate as an increase (or at least a change) inrotor vibration. For any individual casingmeasurement to be effective for overall machineprotection, the system must continually transmit asignificant amount of rotor vibration to themachine casing, or mounting location of thetransducer. |
In addition, be careful to install the accelerometer transduceron the bearing housing or machine casing. Improperinstallation may decrease the transducer amplitude andfrequency response and/or generate false signals that do notrepresent actual vibration. Refer to the appropriateinstruction manuals and Application Notes.Upon request, Bently Nevada provides engineering servicesthat can identify the appropriate machine housingmeasurements and installation assistance if needed.
