The Bently Nevada 190501-00-00-CN is a specialized Velomitor CT (Cooling Tower) velocity transducer designed for industrial machinery condition monitoring. This low-frequency piezo-velocity sensor is engineered to measure casing vibration velocity on equipment that operates at or above 90 RPM, such as cooling tower fans and air-cooled heat-exchanger fan assemblies.

Features

• Low-frequency response optimized for slow-speed machinery.
• Measures casing vibration velocity to detect mechanical faults.
• Compatible with cooling towers and air-cooled heat-exchanger fan assemblies.
• Robust construction for industrial environments.
• Integrated MIL-C-5015 connection interface.

Applications

• Cooling Tower Fans: Detecting imbalances in large, slow-moving fan blades.
• Slow-Speed Agitators: Monitoring vibration in chemical processing or water treatment tanks.
• Industrial Fan Assemblies: Measuring vibration frequencies generated by fan motors and speed reducers.

Technical Specifications

Installation Guidelines

• Ensure the mounting surface is clean, flat, and free of debris to maintain accurate vibration signal transmission.
• Use appropriate shielded cabling to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Verify that the transducer is securely fastened according to the specific mounting configuration (No stud/adapter).
• Always power down the monitoring system before connecting or disconnecting the sensor to prevent electrical damage.
• Route signal cables away from high-voltage power lines and variable frequency drive (VFD) output cables.
