Features:
- The 190501-02-00-04 features low-frequency design for cooling tower and heat-exchanger applications.
- This model includes stud mounting hardware with 3/8-24 to 1/2-20 thread adapter.
- The 190501-02-00-04 offers multiple hazardous area approvals including CSA, ATEX, and IECEx.
The 190501-02-00-04 provides essential vibration monitoring functions for slow-speed rotating equipment in explosive environments. This transducer accurately measures vibration amplitudes at low frequencies as well as the vibration frequencies generated by the fan motor and speed reducer. The 190501-02-00-04 carries multiple international approvals including CSA/NRTL/C for Class I, Division 1 and ATEX/IECEx/CSA for Class I, Zone 0/1 hazardous areas, directly affecting its suitability for global deployment in classified locations.
For comprehensive machinery health monitoring, the 190501-02-00-04 delivers reliable vibration data that supports predictive maintenance programs while maintaining hazardous area compliance. The MIL-C-5015 connection interface on the 190501-02-00-04 ensures reliable signal transmission without compromising the explosion-proof rating. This transducer enables early detection of developing faults in fan assemblies operating in the 100 to 300 rpm range where standard sensors cannot provide accurate measurements.
The 190501-02-00-04 represents Bently Nevada's specialized solution for monitoring slow-speed rotating equipment in hazardous areas worldwide. This transducer provides the sensitivity and frequency response necessary to detect developing faults before catastrophic failures occur. The 190501-02-00-04 ensures reliable operation of critical cooling assets through accurate, low-frequency vibration measurement with comprehensive hazardous area certifications.
The 190501-02-00-04 Bently Nevada Velomitor CT Velocity Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Cooling Towers & Air-cooled Heat Exchangers: This is its core application. Specifically designed to monitor low-speed fan assemblies, providing early warning of blade imbalance or bearing failure.
- Low-Speed Rotating Machinery: Suitable for industrial equipment operating at speeds between 100 and 300 rpm, such as large low-speed fans, slow-speed pump sets, and mixers.
- Casing Vibration Monitoring: Measures the vibration velocity of casings in equipment equipped with rolling element bearings for condition monitoring and fault diagnosis.
- Sensor Side: The 190501 is an analog piezoelectric sensor. It does not contain programmable logic or a processor, therefore the sensor itself does not require or support firmware updates.
- System Side: To improve monitoring accuracy or compatibility, updates should be applied to the connected monitoring system module (such as the 3500 series module). Users must obtain the latest module firmware through the Bently Nevada official service portal and flash it using the configuration software.
- Calibration Recommendations: Due to its low-frequency characteristics, it is recommended to periodically verify sensitivity using a dedicated low-frequency vibration calibrator (such as the Model 9110D) rather than compensating for attenuation through software updates.
- Location: Should be installed on the bearing housing or in the housing location that best reflects rotor vibration.
- Surface Requirements: The mounting surface must be flat (flatness within 0.001 inches). 1/2-20 UNF bolts are recommended (determined by -02 in the code).
- Torque: Tighten with a torque of 33 to 47 Newton-meters (N·m) to ensure complete coupling between the sensor and the surface.
