Quick Detail

Description

The 190501-07-00-01 Velomitor CT Velocity Transducer is a high-precision, low-frequency piezo-velocity sensor engineered for accurate vibration monitoring on industrial machinery, particularly cooling tower and air-cooled heat exchanger fan assemblies operating at 90 rpm and above. The transducer features a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, a frequency response of 3 Hz to 900 Hz ±1 dB, and a robust 316L stainless steel case, ensuring reliable performance in harsh operating conditions. With a MIL-C-5015 2-pin connection interface, universal mounting torque of 4.5 N·m ±0.6 N·m, and compatibility with any mounting orientation, the Velomitor CT provides highly flexible installation. Its operating temperature range from -40°C to +85°C and shock survivability up to 5000 g pk make it suitable for industrial fan monitoring, vibration analysis, and predictive maintenance programs. Certified under CSA/NRTL/C, ATEX, and IECEx standards, it meets safety requirements for Class I Division 1 and Zone 0/1 hazardous locations. This transducer accurately measures both vibration amplitudes and frequencies induced by fan motors and speed reducers, delivering precise condition monitoring data critical for operational reliability and reduced maintenance downtime.

Applications

1. Cooling Tower Fan Vibration Monitoring
Measures low-frequency vibrations in fans operating 100–300 rpm, providing early detection of imbalance, misalignment, or mechanical wear.

2. Air-Cooled Heat Exchanger Performance Analysis
Monitors casing vibration to ensure heat exchangers operate within optimal vibration thresholds, preventing structural fatigue.

3. Fan Motor and Speed Reducer Diagnostics
Captures vibration frequency data from motor and gear assemblies, enabling condition-based maintenance to reduce unplanned downtime.

4. Predictive Maintenance for Industrial HVAC Systems
Integrates with monitoring systems to track long-term vibration trends, allowing scheduled maintenance based on actual equipment condition.

5. Hazardous Location Machinery Monitoring
Certified for Class I Division 1 / Zone 0/1 installations, allowing safe deployment in explosive or flammable environments.

Specifications

Competitive Advantage

1. High Sensitivity and Low-Frequency Accuracy
With a sensitivity of 3.94 mV/mm/s and response down to 3 Hz, the sensor detects minute vibrations in slow-moving fan systems.

2. Rugged Construction
316L stainless steel housing withstands harsh industrial environments and shock loads up to 5000 g pk, ensuring long-term durability.

3. Flexible Mounting
Supports any orientation and a mounting torque of 4.5 N·m ±0.6 N·m, making installation on diverse fan assemblies simple and reliable.

4. Hazardous Location Compliance
Multiple approvals (CSA/NRTL/C, ATEX, IECEx) allow deployment in explosive atmospheres without additional protective measures.

5. Precision Data for Predictive Maintenance
Captures both amplitude and frequency of vibrations from fan motors and reducers, supporting real-time monitoring and predictive maintenance strategies.
