Quick Detail

Description

The 21000-27-05-40-026-03-02 Proximity Probe Housing Assembly is a precision-engineered enclosure designed for externally mounting 3300 XL NSv proximity probes in automated industrial systems. Constructed with a robust aluminum body and a 304 stainless steel sleeve, this housing provides superior mechanical protection while maintaining compliance with CSA hazardous area approvals. The assembly supports a probe cable length of 0.5 m (20 in), a standoff adapter of 4.0 in, and probe penetration of 2.6 in, ensuring precise alignment for vibration and position monitoring applications. Equipped with threaded ports for conduit connections, optional standoff adapters, and versatile fittings—including 3/4-14 NPT plugs, reducers, and cable seal grips accommodating multiple cable sizes—the 21000 housing offers flexible installation in critical automation environments. Lightweight at 1.1 kg (2.4 lb) without fittings, this housing is designed to meet the API 670 Standard for externally mounted proximity probes, providing reliable performance under harsh conditions. Its all-metal construction ensures resistance to mechanical stress and vibration, while optional CSA-certified intrinsically safe probes allow deployment in hazardous locations, making the 21000 Proximity Probe Housing Assembly ideal for advanced industrial automation monitoring and control.

Applications

1. Rotating Equipment Vibration Monitoring
Installed on turbines, pumps, and compressors, the 21000 housing ensures accurate proximity probe positioning to monitor vibration levels. The 2.6 in penetration allows optimal proximity sensor alignment, reducing false alarms in high-speed rotating machinery.

2. Automated Bearing Health Assessment
With a 4.0 in standoff adapter, the assembly enables proper placement of 3300 XL NSv probes to measure shaft displacement and bearing wear in real time. Data accuracy supports predictive maintenance schedules and reduces unexpected downtime.

3. Hazardous Area Automation Systems
The CSA-certified 21000 housing supports intrinsically safe probes for explosive or flammable environments. It is rated for Type 4 enclosures, allowing integration into automated control systems in chemical, oil, and gas processing facilities.

4. API 670 Compliant Machinery Protection
Compliant with API 670, this housing is suitable for automated monitoring of critical process machinery. The robust aluminum and stainless steel construction withstands harsh operational conditions, including high vibration and temperature variations.

5. Custom Probe Deployment in Compact Spaces
Optional standoff adapters and multiple fittings allow flexible installation in limited spaces while maintaining probe alignment. Sleeve lengths up to 12 in can be safely supported with additional supports, enabling precise automation monitoring even in constrained machinery layouts.
