Quick Detail

Description

The 190501-11-00-04 Velomitor CT Velocity Transducer is a precision low-frequency piezo-velocity sensor designed for industrial automation and rotating equipment monitoring. Engineered to accurately measure casing vibration velocity on cooling tower and air-cooled heat exchanger fan assemblies operating at speeds of 90–300 rpm, it provides reliable vibration data critical for predictive maintenance and equipment protection. The sensor offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, with a frequency response ranging from 3 Hz to 900 Hz (±1 dB), ensuring accurate detection of both low and medium-frequency vibration signals. Constructed from 316L stainless steel, the transducer withstands harsh environmental conditions with -40°C to +85°C operating range and up to 5000 g shock resistance. The unit features a MIL-C-5015 2-pin connector, supports any mounting orientation on a 33 mm diameter surface, and is certified for hazardous locations under CSA/NRTL/C (Class I, Division 1), ATEX/IECEx (Zone 0/1). This design ensures high reliability in demanding industrial settings, providing consistent vibration monitoring for automation systems, fans, and rotating machinery.

Applications

Cooling Tower Fan Vibration Monitoring
Measures casing vibration velocity on large cooling tower fans operating at 90–300 rpm, helping prevent fan imbalance and mechanical failure.

Air-Cooled Heat Exchanger Monitoring
Provides low-frequency vibration analysis to detect early mechanical wear in heat exchanger fan assemblies.

Predictive Maintenance Systems
Integrates with industrial automation platforms to trigger maintenance actions before equipment damage occurs, improving operational uptime.

Fan Motor and Speed Reducer Analysis
Monitors vibration frequencies generated by fan motors and gear reducers, ensuring smooth and safe operation.

Industrial Rotating Equipment Diagnostics
Supports monitoring of pumps, blowers, and compressors with low-frequency vibration signals for comprehensive machinery health assessment.

Specifications

Competitive Advantage

High Sensitivity and Accuracy
With 3.94 mV/mm/s sensitivity and ±5% tolerance, the sensor detects low-amplitude vibrations reliably.

Wide Low-Frequency Response
Frequency range of 3–900 Hz (±1 dB) allows accurate measurement of slow-turning fan assemblies that standard sensors might miss.

Robust Industrial Construction
316L stainless steel housing and 5000 g shock rating provide durability in harsh and high-shock environments.

Hazardous Location Certification
Certified to CSA/NRTL/C, ATEX, and IECEx standards, enabling safe operation in explosive or flammable environments.

Flexible Installation
Supports any mounting orientation on a 33 mm surface with precise torque control, simplifying installation in constrained or complex machinery.
