Product Overview
The CA21000-28-05-00-113-03-02 explosion-proof housing assembly from Bently Nevada protects proximity probe connections in hazardous industrial environments exposed to explosive gas, dust, vibration, and moisture. Refineries, LNG terminals, offshore platforms, chemical processing facilities, and power generation plants commonly install this assembly to safeguard vibration monitoring systems operating around turbines, compressors, motors, and pumps.
This housing assembly supports the 3300 XL 8 mm probe system and provides secure cable routing and environmental sealing for machinery protection applications. The aluminum housing combined with a 304 stainless steel sleeve improves corrosion resistance in demanding industrial conditions. The supplied NPT fittings and cable seal grips simplify field installation while maintaining hazardous area protection integrity. The 11.3 in probe penetration configuration supports deep mounting arrangements commonly found in compressor casings and turbine bearing housings where reliable vibration monitoring directly affects equipment availability and shutdown prevention.

Technical FAQs
What is the primary function of the explosion-proof housing assembly?
The housing assembly protects probe connections and cable terminations in hazardous industrial environments where explosive gas or dust may exist.
Can this housing support 3300 XL proximity monitoring systems?
Yes. The assembly is designed for use with 3300 XL 8 mm proximity probes in machinery protection applications.
Why does the assembly use both aluminum and stainless steel materials?
The aluminum body reduces weight while the 304 stainless steel sleeve improves corrosion resistance and mechanical durability in industrial environments.
What installation environments typically require this housing assembly?
Refineries, offshore platforms, LNG facilities, chemical plants, and compressor stations commonly require explosion-proof housings for hazardous area compliance.
Engineering & Installation Guide
Verify hazardous area sealing integrity after cable routing and fitting installation. Improper cable gland tightening may compromise explosion-proof protection performance.
Install the housing away from excessive radiant heat sources when possible. High external surface temperatures may affect long-term cable sealing reliability.
Use proper thread sealant approved for hazardous area applications on all NPT connections. Incorrect sealing compounds may reduce enclosure protection capability in explosive environments.
