Product Overview

The Bently Nevada 190501-04-00-04 is a Velomitor CT velocity transducer intended for absolute vibration measurement on machine casings and bearing housings. It converts casing vibration velocity into a proportional electrical output, supporting continuous condition monitoring and machinery protection programs.

This configuration is commonly selected for low-speed rotating equipment where vibration velocity at low fundamental frequencies must be captured with good stability. Typical installations include large cooling-tower fans and air-cooled heat-exchanger (ACHE) fan decks, where the primary running speed and related drivetrain frequencies need to be trended for early fault identification.
