The 190501-14-99-00 Velomitor CT Velocity Transducer is a low-frequency version of the standard Velomitor Piezo-velocity Sensor, specifically designed to measure casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies operating at 90 rpm or higher (typically 100 to 300 rpm). It effectively captures vibration amplitudes at these frequencies, as well as those generated by the fan motor and speed reducer.

Installation Guidelines
-Proper Placement – Install the accelerometer transducer on the bearing housing or machine casing to ensure accurate readings.
-Avoid Signal Distortion – Incorrect installation may reduce amplitude and frequency response or create false signals that do not reflect actual vibration levels.
-Reference Documentation – Follow the instruction manuals and application notes for proper setup.

Engineering Support
Bently Nevada offers engineering services upon request, providing expert assistance in determining the correct installation locations and ensuring optimal sensor performance.
