Quick Detail

Description

The 21000-16-05-20-033-00-02 Proximity Probe Housing Assembly is a robust, all-metal external mounting solution designed for industrial automation and rotating machinery condition monitoring systems. Engineered to house a 3300 XL 8 mm proximity probe with a 0.5 m probe cable, this proximity probe housing assembly provides reliable mechanical protection and precise probe positioning in demanding plant environments.
Featuring a 3/4-14 NPT mounting thread, a 3.0 in probe penetration, and a 2.0 in standoff adapter, the 21000 Proximity Probe Housing Assembly supports accurate installation on pumps, compressors, turbines, and motors where internal mounting is not feasible. The aluminum body combined with a 304 stainless steel sleeve offers an optimal balance of lightweight construction and corrosion resistance. With a typical weight of 1.1 kg and compact overall dimensions, this proximity probe housing assembly integrates seamlessly into automation systems that require compliance with API 670 standards and explosion-proof enclosure requirements. Its modular design allows flexible configuration for different sleeve lengths and installation constraints, making it a dependable choice for continuous vibration and displacement monitoring in automated industrial facilities.

Applications

The 21000 Proximity Probe Housing Assembly is primarily used for external mounting of proximity probes on critical rotating equipment in oil and gas, petrochemical, power generation, and general industrial automation plants. It is ideal for applications such as shaft radial vibration measurement, shaft position monitoring, and axial displacement detection on centrifugal compressors, pumps, and turbines.
With a 3.0 in probe penetration and compatibility with 3300 XL 8 mm probes, the housing ensures stable signal acquisition even in hazardous areas. The CSA Type 4 rated enclosure and explosion-proof design enable safe operation in classified zones, supporting intrinsically safe automation systems and continuous machine protection programs.

Specifications

Competitive Advantage

The 21000 Proximity Probe Housing Assembly delivers strong competitive advantages through its API 670 compliance, explosion-proof rating, and modular all-metal construction. Compared with non-certified housings, it provides higher safety margins for hazardous environments while maintaining precise probe alignment.
The combination of an aluminum housing and stainless steel sleeve reduces overall weight without compromising durability, improving installation efficiency. Flexible sleeve length options and compatibility with existing 3300 XL proximity probes lower retrofit and upgrade costs in automation systems. These features make the 21000 Proximity Probe Housing Assembly a reliable, standards-compliant, and cost-effective solution for long-term industrial condition monitoring and automated machinery protection.
