Quick Detail

Description

The 190501-11-00-00 Velomitor CT Velocity Transducer is a precision low-frequency piezo-velocity sensor designed for industrial automation and machinery monitoring applications. Specifically engineered to measure casing vibration velocity on cooling towers, air-cooled heat exchangers, and fan assemblies, this transducer provides accurate velocity measurements for equipment operating at 90–300 rpm, capturing both slow rotational motions and higher frequency vibrations generated by motors and speed reducers. With a sensitivity of 3.94 mV/mm/s ±5% and a frequency response range of 3 Hz to 900 Hz (or up to 1 kHz at ±3 dB), the Velomitor CT ensures reliable detection of subtle vibration amplitudes critical for predictive maintenance and performance optimization. Constructed from 316L stainless steel with a robust MIL-C-5015 two-pin top connector, it operates in temperatures from -40°C to +85°C, withstanding shocks up to 5000 g and 100% condensing humidity conditions. The sensor’s design allows mounting on a 33 mm diameter surface with any orientation, providing flexible installation in constrained industrial environments. Its durable, corrosion-resistant construction ensures long-term reliability and accurate vibration monitoring across demanding industrial processes.

Applications

1. Cooling Tower Fan Vibration Monitoring
Measures low-frequency vibration velocity of cooling tower fan casings (90–300 rpm), enabling predictive maintenance and early detection of imbalance or misalignment.

2. Air-Cooled Heat Exchanger Analysis
Captures vibration amplitudes caused by fan motors and speed reducers, helping engineers diagnose operational anomalies and prevent mechanical failures.

3. Motor and Gearbox Vibration Detection
Provides precise velocity measurements of motor casings, gear reducers, and shafts, ensuring optimal performance and reduced downtime.

4. Structural Health Monitoring
Monitors vibrations transmitted to supporting structures, allowing assessment of machine mounting integrity and foundation stability in industrial facilities.

5. Automated Machinery Feedback Systems
Integrates with PLCs and control systems to provide real-time vibration data for automated monitoring, diagnostics, and predictive maintenance routines.
