Description

Technical Overview

The Bently Nevada 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly is a precision-engineered component designed for demanding industrial condition monitoring applications. As part of the industry-standard 3300 XL series ecosystem, this housing assembly ensures optimal mechanical integration, electromagnetic shielding, and thermal stability for high-fidelity vibration and position measurements in rotating machinery. It is engineered to maintain consistent probe-to-target gap integrity under extreme operating conditions—including high temperatures, heavy vibration, and corrosive environments—making it ideal for use in gas turbines, steam turbines, compressors, motors, and pumps across power generation, oil & gas, and process manufacturing sectors.

Constructed from rugged stainless steel with a hermetically sealed design, the housing provides robust protection against moisture ingress (IP67-rated), particulate contamination, and mechanical impact. Its precisely machined internal geometry ensures accurate alignment and repeatable installation of the associated 3300 XL proximity probe, minimizing measurement drift and maximizing system reliability over extended service life. The assembly complies with API 670 (4th Edition) standards for machinery protection systems and supports seamless integration with Bently Nevada’s 3500/3300 monitoring platforms, enabling real-time asset health assessment and predictive maintenance strategies.
