Features:

  • Low-frequency velocity transducer for cooling tower fans
  • Plate stud mounting with MIL-C-5015 connector
  • Hazardous area certified (CSA, ATEX, IECEx)
The 190501-12-00-05 provides essential vibration sensing functions critical to the entire monitoring path, serving as the primary interface between slow-speed rotating machinery and the protection system, directly affecting the proper, normal operation of the overall asset monitoring program. One 190501-12-00-05 transducer is required per measurement point, installed on the casing of cooling tower fans or air-cooled heat exchangers using the plate stud mounting hardware that accommodates both 3/8-24 imperial and M8x1 metric thread requirements.

For applications requiring comprehensive fan assembly monitoring, the 190501-12-00-05 measures vibration amplitudes at the fundamental fan frequencies as well as the vibration frequencies generated by the motor and gearbox. In addition to standard velocity measurement, the robust construction of the 190501-12-00-05 ensures reliable operation in the challenging environmental conditions typical of cooling tower applications, including moisture, temperature variations, and airborne contaminants.

The 190501-12-00-05's hazardous area certifications ensure compliance with international safety standards for installations in potentially explosive environments. Using certified materials and construction techniques, the transducer delivers consistent performance in petrochemical facilities, refineries, and other industrial sites where cooling assets are located.

The 190501-12-00-05 Bently Nevada Velocity Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Model 190501-12-00-05 is a specialized low-frequency velocity transducer engineered for monitoring casing vibration on cooling tower and air-cooled heat-exchanger fan assemblies. This instrument is a dedicated low-frequency version of the standard Velomitor Piezo-velocity Sensor, specifically optimized for applications where fan speeds operate at or above 90 rpm, with typical operating ranges of 100 to 300 rpm. 

The measurement capabilities of the 190501-12-00-05 extend across the full vibration spectrum produced by cooling tower fan assemblies. By capturing both the low-frequency components from the slow-speed fan rotation and the higher-frequency signatures from the motor and gearbox, the 190501-12-00-05 enables early detection of developing faults such as imbalance, misalignment, bearing wear, and gear deterioration. 

Installation flexibility is provided by the plate stud mounting hardware on the 190501-12-00-05, which accommodates both 3/8-24 imperial and M8x1 metric thread requirements. The MIL-C-5015 connection interface on the 190501-12-00-05 ensures a rugged, reliable electrical connection that maintains signal integrity in the challenging environmental conditions typical of cooling tower applications, including moisture, temperature variations, and airborne contaminants. 

Hazardous area certification is a critical feature of the 190501-12-00-05, which carries multiple international approvals including CSA/NRTL/C for Class I, Division 1 locations, and ATEX/IECEx/CSA for Class I, Zone 0/1 explosive atmospheres. These certifications on the 190501-12-00-05 permit installation in potentially explosive environments commonly found in petrochemical facilities, refineries, and other industrial sites where cooling towers and air-cooled heat exchangers are located.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the primary application and speed range for the 190501-12-00-05 velocity transducer?
The 190501-12-00-05 is specifically designed for measuring casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies that operate at or above 90 rpm, with typical operating speeds of 100 to 300 rpm. This low-frequency version of the standard Velomitor sensor accurately measures vibration amplitudes at these slow rotation speeds as well as the higher frequencies generated by the fan motor and speed reducer, providing comprehensive monitoring of the entire fan drive train.
What mounting hardware and connection interface are provided on the 190501-12-00-05?
The 190501-12-00-05 features plate stud mounting hardware that accommodates both 3/8-24 imperial and M8x1 metric thread requirements, providing installation flexibility across different equipment types. The transducer utilizes a MIL-C-5015 connection interface, which is a rugged industrial-grade connector that ensures reliable electrical connections in challenging environmental conditions typical of cooling tower applications, including moisture, temperature variations, and airborne contaminants.
What hazardous area approvals does the 190501-12-00-05 carry?
The 190501-12-00-05 carries multiple international hazardous area approvals including CSA/NRTL/C certification for Class I, Division 1 locations, and ATEX/IECEx/CSA certifications for Class I, Zone 0/1 explosive atmospheres. These certifications permit installation of the 190501-12-00-05 in potentially explosive environments commonly found in petrochemical facilities, refineries, and other industrial sites where cooling towers and air-cooled heat exchangers are located.
How does the 190501-12-00-05 differ from the standard Velomitor sensor?
The 190501-12-00-05 is a low-frequency version of the standard Velomitor Piezo-velocity Sensor, specifically optimized for slow-speed applications such as cooling tower fans operating at 100-300 rpm. While the standard Velomitor is designed for general-purpose machinery monitoring, the 190501-12-00-05 provides enhanced low-frequency response to accurately measure vibration at these reduced speeds while maintaining the ability to capture higher frequencies from the motor and speed reducer, ensuring complete vibration monitoring of the entire fan assembly.
