Product Description:
The Bently Nevada 190501-07-99-01 is a Velomitor CT (Cooling Tower) Velocity Transducer explicitly engineered for monitoring low-frequency casing vibration. It targets slow-speed industrial machinery that operates at or above 90 RPM. 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.
Application:
Oil & Gas Refineries: Monitoring essential process cooling towers and hazardous-zone fin-fans.
Petrochemical & Chemical Plants: Protecting large reactor-cooling machinery and chemical-separation fan units.
Power Generation Plants: Monitoring cooling infrastructure in coal-fired, combined-cycle, and geothermal facilities.
Water & Wastewater Treatment:Tracking low-speed aeration fans and secondary cooling machinery
Frequently Asked Questions (FAQ)
Q:What is the primary application for this sensor?
A:It is custom-built for cooling tower fans and air-cooled heat exchangers. It excels at monitoring low-speed machinery operating at or above 90 RPM to identify imbalances, structural misalignments, or gear malfunctions.
Q:Is it a direct replacement for other Velomitor models?
A:Yes. It features the standard 100 mV/in/s scaling used across standard Bently Nevada velocity lines. However, unlike standard Velomitors, the CT version is uniquely tuned to capture ultra-low-frequency vibrations (1.5 Hz to 3 Hz) generated by slow-moving fan blades.
Q:Do I need to recalibrate my monitor system when installing it?
A:No. Because the scale factor matches default industry velocity cards, you can swap it into existing 3500-series or 1900-series monitors without adjusting background logic. A quick loop check to verify the bias voltage (10.1 Vdc ± 1.0 Vdc) is recommended.
