Bently Nevada 21000-16-05-00-062-03-02 21000 Series Proximity Probe Housing Assembly

Description

Designed to provide physical protection and environmental sealing for proximity transducers, the Bently Nevada 21000-16-05-00-062-03-02 is a rugged probe housing assembly configured for industrial machinery monitoring. Built with an anodized aluminum body and a high-grade 304 stainless steel sleeve, this mechanical protective dome shields critical proximity probes from aggressive industrial environments, moisture, and mechanical damage. The integration of specialized cable seals and mounting options ensures seamless deployment on steam turbines, compressors, and high-speed rotating machinery casings.

Features

• Engineered Protection: Combines a lightweight aluminum housing body with a robust 304 stainless steel sleeve.
• Optimized Probe Compatibility: Specially designed for seamless integration with a 3300 XL 8 mm proximity probe.
• Direct Mount Configuration: Features a 3/4-14 NPT mounting thread option with zero standoff adapter requirement.
• Flexible Cable Entry: Outfitted with multiple grommet options to securely seal varying field cable diameters.
• Robust Environmental Seal: Prevents industrial process contaminants and moisture from degrading probe connections.

Applications

• Industrial steam and gas turbine shaft vibration and expansion monitoring.
• Hydroelectric generator shaft alignment and radial displacement measurement.
• High-pressure process compressor and pump vibration protection networks.
• Corrosive or high-humidity heavy manufacturing environments demanding mechanical transducers protection.

Empirical Engineering Insights

Alternative Models & Compatibility

This 21000 housing configuration is tailored for the 3300 XL 8 mm transducer line. If retrofitting an older 7200 series transducer setup, do not attempt to force the probe into the sleeve, as the internal dimensions and shoulder stops differ. Verify sleeve inner diameter clearance prior to insertion.

Application Pitfalls & Engineering Notes

Operating in environments with highly corrosive acidic gases can accelerate galvanic corrosion between the aluminum body and the stainless steel sleeve if moisture pools around the threads. In such installations, ensure thread lubricants with active anti-corrosion inhibitors are applied uniformly during assembly.

Commissioning & Wiring Tips

Always insert the probe and route its integrated 0.5-meter cable through the sleeve and cable grip BEFORE securing the housing into the machine casing. Spinning the housing with the probe pre-installed and wired will twist the coaxial cable, leading to micro-fractures in the conductor shield and subsequent signal degradation.
