Bently Nevada 330180-X0-05 Proximity Probe & 145004-04 Proximitor Module

Introduction / Technical Overview

The Bently Nevada 330180-X0-05 Proximity Probe and 145004-04 Proximitor Module form a complementary pair for precise radial shaft displacement and vibration monitoring. The probe senses the gap between the rotating shaft and the bearing housing, while the proximitor converts this signal into a conditioned voltage compatible with Bently Nevada monitoring racks.

Together, these modules provide a reliable, industrial-grade solution for machinery protection, orbit analysis, and predictive maintenance in turbines, compressors, pumps, and generators. Their design emphasizes robust field performance, ease of integration, and stable, repeatable measurement under harsh operating conditions.

Technical Specifications

Applications / Use Scenarios

• Installed in turbines, compressors, and pumps for radial shaft displacement monitoring.
