Product Overview
The Bently Nevada 190501-08-00-00 Velomitor CT Velocity Sensor is a specialized vibration monitoring sensor designed for measuring casing vibration velocity in rotating machinery. As part of the renowned Velomitor CT (Cooling Tower) series, this sensor is optimized for low-frequency vibration measurement, making it particularly suitable for cooling tower fans, air-cooled heat exchangers, and other slow-speed rotating equipment.
Unlike conventional vibration sensors, the Velomitor CT is specifically engineered to accurately detect vibration levels in machinery operating at relatively low rotational speeds, providing valuable condition monitoring data for predictive maintenance programs.

Function and Working Principle
The 190501-08-00-00 is designed to continuously monitor machinery vibration by converting mechanical vibration velocity into an electrical output signal.
Main Functions
- Measures machine casing vibration velocity
- Detects imbalance and misalignment conditions
- Monitors bearing and gearbox health
- Supports predictive maintenance programs
- Provides early warning of mechanical faults
Working Principle
The Velomitor CT utilizes an integrated piezoelectric sensing element that generates an electrical signal proportional to the vibration velocity of the monitored equipment. The sensor is mounted directly to the machine housing, where it continuously measures vibration levels and transmits the signal to monitoring systems.
Because the frequency response is optimized for low-speed machinery, the sensor can accurately measure vibration on equipment operating as low as 90 RPM, making it particularly effective for cooling tower and heat exchanger fan applications.
