Quick Detail

Description

The Velomitor CT Velocity Transducer (190501-01-00-00) is a precision low-frequency piezo-velocity sensor engineered for industrial automation and vibration monitoring applications. Specifically designed to measure casing vibration velocity on cooling towers and air-cooled heat exchanger fan assemblies, it effectively operates at fan speeds at or above 90 rpm, with optimal performance in the 100–300 rpm range. This transducer accurately captures vibration amplitudes and frequencies generated by fan motors and speed reducers, enabling predictive maintenance and real-time condition monitoring in complex industrial environments.

Constructed with 316L stainless steel, the Velomitor CT ensures long-term durability under harsh conditions, including operating temperatures from -40°C to +85°C and shock limits up to 5000 g. Its frequency response of 3.0 Hz to 900 Hz (±1 dB) or 1.5 Hz to 1 kHz (±3 dB) allows precise detection of low-frequency vibrations critical for fan system efficiency and reliability. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s ±5%), this transducer integrates seamlessly into automated monitoring systems using a MIL-C-5015 2-pin connector and versatile mounting angles on 33 mm diameter surfaces.

Applications

1. Cooling Tower Fan Monitoring
The Velomitor CT measures fan vibration velocities in air-cooled condenser systems, ensuring early detection of bearing wear or imbalance. Its frequency response up to 1 kHz allows capturing both slow fan oscillations and motor-induced harmonics for precise performance analysis.

2. Heat Exchanger Fan Assemblies
Used on industrial heat exchangers, it provides continuous vibration data to detect misalignment or blade resonance. Case studies show up to 15% reduction in unplanned downtime when integrated into automated monitoring systems.

3. Predictive Maintenance in HVAC Systems
By monitoring low-frequency vibrations of large HVAC fans, the sensor enables condition-based maintenance programs, extending component life and reducing energy consumption by 8–12% on average.

4. Motor and Gearbox Condition Monitoring
The transducer captures vibration amplitudes from speed reducers and fan motors, allowing real-time analysis of gear wear, lubrication status, and mechanical integrity, reducing repair costs by up to 20%.

5. Industrial Automation Data Integration
Compatible with SCADA and DCS systems, the Velomitor CT feeds vibration data for automated control, enabling asset optimization and energy efficiency improvements in process industries.
