The 24701 stainless steel housing is a rugged assembly designed for critical rotating assets such as steam turbines, centrifugal compressors, and large industrial pumps. It strictly adheres to API 670 standards, providing a professional-grade interface for monitoring radial vibration and axial position in high-stakes machinery environments.
This specific configuration features a 10.5-inch (267 mm) penetration length and a 3/4-14 NPT mounting thread, making it compatible with deep-bore bearing housings. The inclusion of a 0.5-inch standoff adapter ensures there is sufficient clearance for external cabling and connector protection, allowing for seamless integration into diverse machine frame designs.
A primary operational advantage is the ability to perform external probe gap adjustments without shutting down the target machinery. This "live adjustment" capability significantly reduces maintenance downtime and enhances safety, as technicians can optimize the 3300 XL 8 mm probe’s position while the machine remains in full operation.
Engineered for "Application Factories" such as offshore oil platforms and chemical processing plants, the housing is constructed from 303 and 304 stainless steel. This premium material selection provides exceptional resistance to salt spray, high humidity, and corrosive atmospheric contaminants that would typically degrade standard aluminum housings.
The assembly is fully certified for hazardous areas, meeting CSA (Class I, Div 1 & 2) and ATEX/IECEx safety requirements for explosive atmospheres. Rated as a Type 4 enclosure, it ensures the internal 0.5-meter probe cable and electronic connections remain completely sealed against severe weather and high-pressure industrial washdowns.
For high-vibration environments, the assembly includes specialized cable seal grips and fittings (Option 03) to maintain signal integrity. Since the total extension exceeds 12 inches, this robust design prevents mechanical resonance, ensuring that the 3300 XL 8 mm sensor delivers precise, noise-free data for the facility's machinery protection system.
