Description
The 190501-09-99-00 Velomitor CT Velocity Transducer is a precision low-frequency piezo-velocity sensor designed for industrial automation and condition monitoring of rotating equipment, including cooling towers, air-cooled heat exchangers, and fan assemblies. Engineered for reliable vibration velocity measurement, it provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% and a frequency response range of 3 Hz to 900 Hz (±1 dB), capturing both low-speed fan motion and motor-induced vibrations. The transducer features a robust 316L stainless steel case, a top-mounted 2-pin MIL-C-5015 connector, and comes with a 32-foot cable for flexible installation. It operates from -40°C to +85°C and withstands 5000 g shock peaks, making it suitable for harsh industrial environments. Designed for easy installation on 33 mm diameter mounting surfaces using a plate stud (3/8-24 to 1/4-in NPT) with torque control of 4.5 N-m ±0.6 N-m, the 190501-09-99-00 Velomitor CT ensures accurate, repeatable vibration measurements in any mounting orientation. Its low-temperature sensitivity (-8% to +5%) and 100% condensing humidity tolerance support reliable monitoring for fan speed verification, preventive maintenance, and automated plant safety systems.
Applications
Cooling Tower Fan Vibration Monitoring
Measures vibration velocity on cooling tower fans operating between 100–300 rpm; sensitivity of 3.94 mV/mm/s allows detection of early mechanical issues and blade imbalance.
Air-Cooled Heat Exchanger Diagnostics
Captures low-frequency casing vibrations generated by fans and speed reducers; frequency response up to 900 Hz ensures accurate amplitude and phase monitoring for preventive maintenance.
Motor and Gearbox Vibration Analysis
Monitors vibration from fan motors and speed reducers; 5000 g shock limit protects the transducer against transient mechanical impacts during operation.
Condition-Based Maintenance Integration
Supports integration into SCADA or vibration monitoring systems; 32-foot cable and flexible mounting options reduce installation complexity and downtime.
Environmental Reliability Monitoring
Operates in humid or condensing indoor/outdoor environments (-40°C to +85°C), enabling long-term monitoring of industrial HVAC, cooling, or ventilation equipment.

Competitive Advantage
High Measurement Sensitivity
3.94 mV/mm/s (100 mV/in/s) ±5% provides precise detection of low-speed vibrations and mechanical irregularities on fan and heat exchanger systems.
Wide Low-Frequency Response
Accurate vibration measurement from 3 Hz to 900 Hz (±1 dB), covering both slow fan rotation and higher frequency motor/gear-induced vibrations.
Rugged Industrial Construction
316L stainless steel housing and top-mounted MIL-C-5015 connector offer excellent durability, shock resistance up to 5000 g, and corrosion protection for industrial environments.
Flexible Mounting Options
Mounts to 33 mm diameter surfaces using 3/8-24 to 1/4-in NPT plate studs with controlled torque, allowing installation in any orientation while maintaining signal integrity.
Environmental Stability
Temperature sensitivity of -8% to +5% and 100% condensing humidity tolerance ensures reliable operation in harsh, high-moisture environments typical of cooling towers and air handling equipment.
