Product Overview

The Bently Nevada 31000-28-05-15-042-06-02 is a specialized proximity probe housing assembly designed to facilitate the external mounting and adjustment of 3300 XL series transducers. This assembly is engineered to provide a secure, environmental seal for proximity sensors while allowing maintenance personnel to adjust probe gaps or replace sensors without needing to shut down or disassemble the machinery. By utilizing a ruggedized casing and precise standoff components, this housing protects the delicate sensor tip and cabling from the harsh external conditions found in industrial plants, ensuring continuous and accurate monitoring of critical shaft parameters.

Industrial Applications and Operational Benefits

The 31000 series housing assembly is a critical component for Turbine Supervisory Instrumentation (TSI) and general rotating equipment monitoring.

• Radial Shaft Vibration Securely housing probes used to measure the dynamic motion of shafts in pumps, motors, and fans.

• Keyphasor and Speed Measurements Providing a stable mounting platform for once-per-turn reference sensors required for phase and RPM analysis.

• External Gap Calibration Allowing technicians to perform gap voltage adjustments from outside the machine casing during operation to ensure the sensor remains within its linear range.

• Corrosive Environment Protection Utilizing PPS and stainless steel construction to resist chemical exposure in refineries and offshore platforms.

• High-Moisture Installations The Type 4X rating makes it ideal for cooling tower applications where water ingress is a constant threat to sensor electronics.

By implementing the 31000-28-05-15-042-06-02 housing, industrial facilities can significantly reduce maintenance-related downtime while maintaining high-fidelity data acquisition for their most valuable rotating assets.
