Bently Nevada 330881-16-12-165-07-02 PROXPAC XL Proximity Transducer

Product Introduction

The Bently Nevada 330881-16-12-165-07-02 PROXPAC XL Proximity Transducer is designed for accurate measurement of shaft vibration and position in critical rotating equipment. As part of the PROXPAC XL series, it provides stable and reliable signals for machinery protection and condition monitoring systems.

The unit operates based on eddy current technology, enabling non-contact measurement of shaft displacement. This ensures high repeatability and eliminates mechanical wear. Its rugged construction allows operation in environments with strong vibration, oil contamination, and temperature variations.

It is commonly applied in turbines, compressors, and other high-speed rotating assets where precise monitoring is essential to detect early-stage mechanical issues and avoid unplanned shutdowns.
