Quick Detail

Description

The 21000-28-10-00-041-04-02 Proximity Probe Housing Assembly is a robust industrial-grade aluminum housing designed to mount 3300 XL 8 mm proximity probes for automated machinery monitoring and vibration diagnostics. Featuring a 1.0-meter probe cable and a 4.1-inch probe penetration option, this housing provides reliable external access to proximity probes for gap adjustment or probe replacement without machine disassembly. Constructed with an aluminum body and 304 stainless steel sleeve, the housing ensures durability, corrosion resistance, and mechanical stability in harsh industrial environments. The assembly includes CSA-approved configurations for hazardous areas, meets Type 4 explosion-proof ratings, and is fully compliant with API 670 standards for externally mounted probe housings. Optional standoff adapters and conduit fittings can be added to adapt to diverse installation requirements. The 21000 housing also supports intrinsically safe probes, enabling seamless integration into automated control and safety systems in petrochemical, power generation, and manufacturing facilities.

Applications

Application 1: Vibration Monitoring in Hazardous Locations
The 21000 assembly supports CSA-approved 3300 XL probes in explosion-proof zones, enabling precise vibration monitoring on pumps, compressors, and rotating machinery in Class I Division 2 areas.

Application 2: External Gap Adjustment for Maintenance
Allows external adjustment of the 3300 XL probe tip without disassembling the machine, reducing downtime and enabling real-time maintenance on fluid-film bearings and turbines.

Application 3: Intrinsically Safe Automation Systems
With CSA hazardous area approvals, the housing can be paired with intrinsically safe proximity probes, ensuring compliance with automated safety protocols in petrochemical and industrial plants.

Application 4: Custom Sleeve Length Configurations
Supports variable sleeve lengths up to 304 mm (12 in) or longer with additional supports, making it suitable for long-penetration measurements in large machinery or restricted-access bearing housings.

Application 5: Rotational Speed and Position Sensing
Combined with 3300 XL probes, the 21000 housing facilitates Keyphasor reference and shaft position monitoring for advanced industrial automation, enabling accurate speed measurement and vibration diagnostics.
