Description

The Bently Nevada 190501-04-00-04 is a specialized Velomitor CT (Cooling Tower) Velocity Transducer. This device is an integrating piezoelectric accelerometer with internal electronics, engineered specifically for low-frequency vibration monitoring. It is optimized for measuring casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies that operate at or above 90 RPM. Its robust design allows it to capture vibration amplitudes from the fan motor and speed reducer effectively.

Features

  • Low-frequency vibration monitoring capability.
  • Designed for casing vibration velocity measurement.
  • Optimized for cooling tower and air-cooled heat-exchanger fan assemblies.
  • Constructed from durable 316L stainless steel.
  • Integrated electronics for direct velocity output.
  • CSA/NRTL/C hazardous area approval rating.

Applications

  • Power Generation: Monitoring of cooling tower fans in fossil and hydro plants.
  • Petrochemical & Refining: Critical monitoring for fin-fan assemblies.
  • Chemical Manufacturing: Vibration analysis for agitators, mixers, and slow-speed reactor cooling systems.
  • Mining & Mineral Processing: Ventilation fan monitoring.
  • Pulp & Paper: Slow-speed fans and wastewater aerators.

Technical Specifications

Model 190501-04-00-04
Sensitivity 3.94 mV/mm/s (100 mV/in/s) +/- 5%
Mounting Hardware Stud M6x1 with 3/8-in 24 adapter
Connection Interface MIL-C-5015
Agency Approval CSA/NRTL/C
Operating Temperature -40 degC to +85 degC (-40 degF to +185 degF)
Housing Material 316L Stainless Steel

Installation Guidelines

  • Mounting Surface: Ensure the mounting surface is flat, clean, and at least 33 mm (1.3 inches) in diameter to ensure proper coupling.
  • Torque Requirement: Tighten the sensor to 4.5 N-m +/- 0.6 N-m (40 in-lbf +/- 5 in-lbf).
  • Orientation: The transducer can be mounted in any orientation, though it is recommended to align it with the primary direction of the vibration being monitored (radial or axial).
  • Handling: As a precision instrument, handle with care to avoid damage to the piezoelectric element. Ensure the electrical connector is properly seated and protected from environmental ingress.
