Bently Nevada 190501-00-00-04 Velomitor CT Velocity Transducer

Description

Engineered for industrial vibration monitoring under low-frequency conditions, the Bently Nevada 190501-00-00-04 is a highly specialized Velomitor CT Velocity Transducer. It is commonly deployed to monitor physical displacement and velocity in slow-speed machinery, particularly cooling tower fans. Encased in a rugged, corrosion-resistant 316L stainless steel housing, this sensor reliably captures vibration signatures and transmits them directly to machinery protection systems.

This specific configuration includes multiple agency approvals for deployment in hazardous areas and utilizes a top-mounted 2-pin MIL-C-5015 electrical interface. The transducer operates without a pre-installed mounting stud, enabling custom mechanical integration depending on system requirements. It provides direct compatibility with continuous monitoring racks and distributed control networks to support preventative maintenance programs.

Features

• Industrial Durability: Constructed from hermetically sealed 316L stainless steel to withstand high humidity and corrosive environments.
• Top Connection Interface: Standardized 2-pin MIL-C-5015 connector ensures secure and clean signal pathing.
• Hazardous Location Ready: Outfitted with multiple agency approvals (Option 04) for installation in explosive and volatile atmospheres.
• Cooling Tower Optimized: Tailored frequency response curves designed to isolate low-frequency vibration anomalies.

Applications

• Cooling tower fans and air-cooled heat exchangers
• Slow-speed gearboxes and drive shafts
• Water and wastewater aeration equipment
• Industrial ventilation systems

Installation Guidelines

Proper installation is vital for achieving accurate low-frequency measurements. Ensure the following preparation and installation procedures are met:

• Surface Preparation: The mounting surface must be machined flat to a minimum of 33 mm in diameter to prevent high-frequency attenuation.
• Torque Control: Always use a calibrated torque wrench to secure the transducer. Exceeding the specified 4.5 N-m torque rating can lead to internal sensing element damage, while under-torqueing degrades signal accuracy.
• Cable Protection: Route and secure field wiring with appropriate strain relief to prevent mechanical stress on the MIL-C-5015 connection point. Use conduit or armor in harsh physical environments.

Compliance and Certifications

• Option 04 multiple agency approvals for hazardous environments (includes North American, ATEX, and IECEx certifications for Zone/Class divisions).
