Quick Detail

Description

The 21000-28-05-00-041-03-02 Proximity Probe Housing Assembly is a durable industrial enclosure designed for externally mounting 3300 XL 8 mm proximity probes in hazardous and high-vibration environments. Constructed from a lightweight aluminum body with a 304 stainless steel sleeve, this assembly provides exceptional mechanical protection while maintaining CSA Type 4 explosion-proof certification for intrinsically safe and hazardous area applications. It features a dome cover, threaded conduit ports, and flexible cable sealing options accommodating multiple cable sizes from 1/8 to 3/8 inches. The housing supports probes with selectable hazardous area approvals and incorporates optional standoff adapters and sleeve lengths tailored to installation requirements. Fully compliant with API 670 standards, this probe housing ensures precise sensor alignment, vibration damping, and reliable signal integrity in critical automation monitoring systems. Ideal for mounting proximity probes on turbines, compressors, and pumps, it delivers robust protection against dust, moisture, and mechanical stress while simplifying installation and maintenance.

Applications

Externally Mounted Turbine Probes
The 21000 housing allows safe and secure installation of 3300 XL 8 mm proximity probes on steam and gas turbines, protecting sensors from environmental hazards while maintaining precise axial and radial alignment.

Hazardous Area Automation
With CSA-certified Type 4 explosion-proof rating, the assembly supports intrinsically safe probe installations in hazardous locations, including oil and gas production or chemical processing plants.

Compressor Shaft Monitoring
Provides mechanical protection for proximity probes monitoring compressor rotors. The housing accommodates flexible cable sealing and long sleeves, ensuring accurate measurement even in high-vibration environments.

Long Sleeve Applications
Sleeves longer than 304 mm (12 in) can be supported with optional sleeve supports and oil seals (part number 37948-01), enabling the probe to extend through inner bearing housings without compromising signal accuracy.

Space-Constrained Installations
Compatible with the compact 164818 probe housing, the 21000 assembly allows installation in tight or restricted areas while maintaining robust protection and reliable sensor operation.
