Bently Nevada 330880-28-00-035-01-02 PROXPAC XL Proximity Transducer

Product Introduction

The Bently Nevada PROXPAC XL Proximity Transducer (Model: 330880-28-00-035-01-02) is an integrated eddy current sensing solution designed for direct mounting on rotating machinery. It combines a proximity probe and a precision mounting assembly into a single unit, simplifying installation while ensuring consistent and reliable measurement performance.

This transducer is widely used in industrial applications where accurate monitoring of shaft vibration and position is essential. By eliminating the need for separate probe alignment and mounting components, the PROXPAC XL design reduces installation errors and improves long-term measurement stability.

Engineered for harsh operating environments, this unit offers strong resistance to vibration, temperature fluctuations, and contamination such as oil and dust. It is suitable for turbines, compressors, pumps, and gearboxes, as well as retrofit projects where simplified installation and improved reliability are required.
