Bently Nevada 21000-00-00-00-000-00-02 Proximity Probe Housing Assembly

Description

The Bently Nevada 21000-00-00-00-000-00-02 is an aluminum proximity probe housing assembly designed for the external mounting of proximity probes on industrial rotating machinery. This unit provides a robust, environmentally sealed enclosure that protects the proximity probe and its electrical connections, while enabling precise positioning of the probe tip relative to the target surface for accurate vibration and position monitoring.

This specific model is a base housing unit configured without an integrated probe, sleeve, or conduit fittings. It serves as a mechanical foundation for 3300 XL 8 mm proximity probes, allowing for field-customized installations. The assembly includes the aluminum housing body, a dome cover, O-rings, and a thread seal, with a 3/4-14 NPT mounting thread.

Features

• Aluminum construction for durability in industrial environments.
• Provides environmental protection for proximity probes and cable connections.
• Allows for external probe adjustment and maintenance without machine disassembly.
• Includes a dome cover for secure, sealed access to internal components.
• Compatible with standard 3/4-14 NPT conduit connections.
• Supports precise probe penetration adjustment within a 13 mm range.

Applications

• Oil and Gas Refineries: Protecting vibration monitoring sensors on compressors, pumps, and turbines.
• Power Generation: Safeguarding turbine-generator shaft sensors in hydro, fossil, and nuclear plants.
• Petrochemical Facilities: Shielding probes from volatile or corrosive atmospheres.
• Heavy Manufacturing: Supporting fluid-film bearing machine monitoring in continuous-operation environments.

Technical Specifications

Installation Guidelines

• Ensure the mounting surface is clean and flat to maintain the integrity of the housing seal.
• Route field wiring through the designated 3/4-14 NPT threaded ports.
• Use appropriate cable seal grips or conduit fittings to maintain the weatherproof and explosion-proof rating of the assembly.
• Tighten the dome cover securely using the captive screws to ensure the internal environment remains sealed.
• For probe penetration lengths exceeding 300 mm (12 inches), install additional sleeve support to prevent resonance.
• Always verify the probe-to-target gap during commissioning using the 13 mm adjustment range.

FAQ
