Descripción Reseñas

The Bently Nevada 190501-12-99-04 is a specialized Velomitor CT (Cooling Tower) velocity transducer engineered for low-frequency vibration monitoring. This piezoelectric sensor is optimized to measure casing vibration velocity on rotating machinery, specifically air-cooled heat exchangers and cooling tower fan assemblies operating at speeds of 90 RPM or higher.

Features

Low-frequency response optimized for cooling tower and fan assembly monitoring.
Measures casing vibration velocity to detect mechanical faults in rotating equipment.
Integrated 32-foot cable for simplified field installation.
Includes mounting hardware (12 Plate Stud 3/8-in 24 to M8x1).
Hazardous area certified for Class I, Division 1 and Class I, Zone 0/1 environments.

Applications

Power Generation: Protection for cooling tower fans and auxiliary cooling systems.
Oil & Gas: Monitoring critical cooling systems and heat exchangers.
Petrochemical & Chemical: Ensuring reliability of large-scale air-cooled heat exchangers.
Wastewater Treatment: Continuous vibration monitoring for aeration and cooling fan assemblies.

Technical Specifications

Model	190501-12-99-04
Sensitivity	3.94 mV/mm/s (100 mV/in/s) +/- 5%
Transverse Response	Less than 5% of axial sensitivity
Mounting	Plate Stud 3/8-in 24 to M8x1
Cable	Included 32-foot integral cable
Hazardous Area Approval	CSA/NRTL/C (Class I, Div 1); ATEX/IECEx/CSA (Class I, Zone 0/1)

Installation Guidelines

Mounting: Use the provided 3/8-in 24 to M8x1 stud. Apply a thread sealant such as Loctite 242 to the mounting stud to prevent loosening caused by continuous low-frequency oscillations.
Hazardous Areas: When installing in Class I, Div 1 or Zone 0/1 environments, you must utilize an intrinsically safe (IS) galvanic isolator or zener barrier to ensure compliance.
Handling: As a precision piezoelectric sensor, avoid dropping or subjecting the transducer to high-impact shocks during installation.
Cabling: Route the integral 32-foot cable away from high-voltage power lines to minimize electromagnetic interference (EMI).

FAQs

What is the primary purpose of the 190501-12-99-04?

This transducer is designed to monitor casing vibration on low-speed rotating equipment, specifically cooling tower fans and air-cooled heat exchangers that operate at 90 RPM or above.

What is the sensitivity of this sensor?

The sensor features a standard sensitivity of 3.94 mV/mm/s (100 mV/in/s) with a tolerance of +/- 5%.

Does this model require specific safety barriers?

Yes, for installations in hazardous locations (Class I, Div 1 or Zone 0/1), an approved intrinsically safe galvanic isolator or zener barrier is required.
