Bently Nevada 330881-28-04-083-06-02 PROXPAC XL Proximity Transducer

Description

Designed for demanding industrial environments, the 330881-28-04-083-06-02 is a ruggedized PROXPAC XL proximity transducer assembly manufactured by Bently Nevada. This integrated assembly packages a high-precision proximity probe and its mechanical housing into a single, cohesive unit. It is engineered to monitor shaft vibration, axial position, and speed on critical rotating machinery, providing robust physical protection against mechanical damage and environmental contamination.

By incorporating the 3300 XL 8 mm proximity probe, this assembly delivers accurate, repeatable eddy-current measurements. The configurable mechanical design of the PROXPAC XL system allows engineers to adjust the insertion depth and mounting configuration to fit exact casing geometry, ensuring optimal probe positioning relative to the target surface.

Features

• Integrated housing design protects the probe body and connector from environmental hazards.
• Features a high-performance 3300 XL 8 mm proximity probe for high-resolution eddy current sensing.
• Configurable standoff and penetration depths accommodate varied machine casing designs.
• Supplied with standard NPT fittings and a stainless steel reducer kit for secure, leak-free installation.
• Equipped with multiple hazardous area approvals to ensure safe operation in classified industrial environments.

Applications

• Steam and gas turbine shaft vibration and position monitoring.
• Centrifugal and axial compressor casing installations.
• Industrial pump, fan, and gearbox protection systems.
• Hydroelectric generator shaft alignment and axial displacement tracking.

Installation Guidelines

When installing the PROXPAC XL assembly, ensure the mounting threads are clean and free of debris. Use the supplied 3/4-14 NPT fitting and the stainless steel reducer where necessary to achieve a secure seal. Verify that the 83 mm penetration depth (C dimension) and the 40 mm standoff (B dimension) match the internal clearances of your specific machine casing before final torque is applied. Proper grounding of the probe shield is essential to prevent electromagnetic interference from distorting the vibration signal.
