Bently Nevada 330881-16-06-165-07-02 PROXPAC XL Proximity Transducer

Product Introduction

The Bently Nevada 330881-16-06-165-07-02 PROXPAC XL Proximity Transducer is designed for reliable measurement of shaft vibration and position in rotating equipment. As part of the PROXPAC XL series, it integrates the proximity probe and signal conditioning unit into a single assembly, simplifying installation and reducing system complexity.

Using eddy current technology, it provides non-contact measurement of shaft displacement, ensuring stable performance without mechanical wear. The design supports consistent signal output even in environments with strong vibration, oil contamination, and temperature variation.

It is typically applied in turbines, compressors, and other critical rotating machinery where continuous monitoring is essential for equipment protection and predictive maintenance.
