Bently Nevada 330800-28-00-035-01-02 PROXPAC XL Proximity Transducer

Product Introduction

The Bently Nevada PROXPAC XL Proximity Transducer (Model: 330800-28-00-035-01-02) is an integrated eddy current proximity measurement solution designed for direct mounting on rotating machinery. It combines a proximity probe and mounting assembly into a single pre-engineered unit, reducing installation complexity and improving measurement consistency.

This PROXPAC XL device is used for continuous monitoring of shaft vibration and position in industrial equipment such as turbines, compressors, pumps, and gearboxes. By integrating the probe into a fixed mechanical assembly, it eliminates many alignment and installation variables associated with traditional separate probe configurations.

The design is optimized for stable long-term operation in harsh industrial environments, ensuring reliable signal output even under high vibration, temperature variation, and mechanical stress conditions. It is widely used in both new installations and retrofit applications where simplified mounting and improved reliability are required.
