Quick Detail

Description

The 190501-18-00-00 Velomitor CT Velocity Transducer is a low-frequency piezo-velocity sensing module optimized for automated vibration diagnostics on cooling towers, air-cooled heat exchangers, and slow-speed fan assemblies found in heavy industrial and power generation facilities. With a calibrated sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% and a wide frequency response from 3.0 Hz up to 900 Hz (or 1.5 Hz to 1.0 kHz at ±3 dB), the 190501-18-00-00 delivers reliable velocity measurements for both fan motor vibration and mechanical reducer dynamics at rotational speeds above 90 rpm. Housed in 316L stainless steel and compatible with MIL-C-5015 connectors, the transducer tolerates extreme humidity (100% condensing), −40°C to +85°C operation, and shock loads to 5000 g, making it suitable for outdoor automated monitoring and predictive maintenance systems integrated into SCADA or DCS platforms. Its adaptable mounting options, including 3/8-24 to 1/2-13 threaded adapters, allow straightforward retrofit installation on legacy cooling infrastructure where continuous velocity monitoring enhances asset reliability, reduces forced outages, and supports digital condition-based maintenance strategies.

Applications

Application 1 Cooling Tower Fan Velocity Monitoring
Measures vibration velocity in slow-speed cooling tower fans operating from 90 to 300 rpm, improving fan balancing and blade health diagnostics in power plant and refinery cooling systems.

Application 2 Air-Cooled Heat Exchanger Condition Diagnostics
Detects velocity levels on air-cooling exchangers to identify bearing wear, motor mechanical faults, and gearbox degradation, enhancing uptime for petrochemical and LNG processing units.

Application 3 Speed Reducer and Gearbox Health Assessment
Captures both low-frequency fan vibration and higher-frequency reducer signatures, supporting gearbox failure prediction before torque loss or catastrophic shutdown.

Application 4 Outdoor SCADA-Integrated Predictive Maintenance
316L stainless enclosure and humidity tolerance enable long-term deployment on outdoor cooling assets, allowing SCADA platforms to trend velocity signatures for automated alarm thresholds.

Application 5 Power Generation Thermal Management Systems
Supports condition-based maintenance in power plants where cooling performance directly impacts turbine and generator thermal efficiency, reducing energy loss and operational penalties.

Specifications

Competitive Advantage

Advantage 1 Low-Frequency Response for Slow Rotating Machinery
Frequency capability down to 1.5–3 Hz allows accurate velocity capture at low rotational speeds (>90 rpm), outperforming standard industrial accelerometers in cooling applications.

Advantage 2 Harsh-Environment Mechanical Robustness
Operating temperature of −40°C to +85°C, 5000 g shock limit, and 100% condensing humidity rating provide long service life in outdoor cooling towers with high moisture and wind loading.

Advantage 3 Stainless Steel Industrial Construction
316L material and MIL-C-5015 connector interface prevent corrosion and maintain contact integrity in chemically aggressive atmospheres common in refineries and fertilizer plants.

Advantage 4 Retrofit-Friendly Mounting Flexibility
Adapter-based threading enables drop-in replacement or retrofit upgrade without modifying fan housings, minimizing downtime during cooling system maintenance cycles.

Advantage 5 Enhanced SCADA/DCS Visibility for Maintenance
Velocity-based vibration data improves trending and threshold-based alerts in distributed control or monitoring systems, enabling data-driven maintenance decisions and uptime stability.
