Product Overview
Description
The 21000-34-10-20-058-04-02 Proximity Probe Housing Assembly is a robust all-metal enclosure designed for the external mounting of proximity probes in industrial automation and rotating machinery protection systems. Engineered to support the 3300 XL 8 mm proximity probe, this housing assembly provides reliable mechanical protection, precise probe positioning, and stable signal performance in harsh operating environments.
Featuring a 3/4-14 NPT mounting thread, a 5.8 in probe penetration, and a 2.0 in standoff adapter, the 21000 series housing enables accurate probe alignment for displacement and vibration measurements. The aluminum body combined with a 304 stainless steel sleeve ensures high corrosion resistance while maintaining structural strength under continuous vibration. With a 1.0 m probe cable, integrated connector protection, and compatibility with hazardous area approvals, the 21000-34-10-20-058-04-02 proximity probe housing assembly is fully compliant with API 670 requirements and suitable for explosion-proof and intrinsically safe automation applications in oil, gas, power generation, and petrochemical industries.
Key Functions
Applications
External Mounting of Proximity Probes on Large Rotating Machinery
In turbines, compressors, and pumps where internal mounting is impractical, the 21000 housing enables secure external installation. The 5.8 in probe penetration depth ensures accurate target positioning while maintaining enclosure integrity.
Hazardous Area Monitoring in Oil and Gas Facilities
With support for CSA explosion-proof approvals and intrinsically safe probe configurations, this housing assembly is ideal for Zone-rated environments. The all-metal construction enhances safety compliance in flammable atmospheres.
Shaft Vibration and Radial Displacement Measurement
Paired with a 3300 XL 8 mm proximity probe, the housing maintains precise probe-to-target spacing, supporting high-resolution vibration measurements typically within a 2 mm linear range required by automation protection systems.
Retrofit and Upgrade of Legacy Monitoring Installations
The 3/4-14 NPT threaded interface allows direct replacement of older housings without major mechanical modifications, reducing downtime during monitoring system upgrades.
Automation Systems Requiring API 670 Compliance
Power plants and petrochemical automation systems that mandate API 670-compliant probe mounting benefit from the standardized geometry and certified enclosure design of the 21000 housing series.

Compatibility & Ordering Notes
Competitive Advantage
All-Metal Construction for Long-Term Reliability
The combination of an aluminum housing body and 304 stainless steel sleeve provides enhanced resistance to corrosion, mechanical stress, and thermal cycling, extending service life in continuous-duty automation environments.
Optimized Probe Alignment and Stability
The defined 2.0 in standoff adapter and controlled sleeve length reduce probe misalignment and vibration-induced measurement errors, improving signal repeatability over long operating periods.
Hazardous Area Certification Support
Compatibility with CSA Type 4 enclosure ratings and intrinsically safe probe options enables deployment in classified areas without additional protective enclosures.
API 670 Compliance for Critical Machinery Protection
Designed to meet API 670 standards, the housing assembly ensures consistent installation practices and regulatory compliance across turbine and compressor protection systems.
Flexible Installation and Expansion Capability
The modular sleeve design allows customized probe penetration lengths. For sleeves longer than 304 mm (12 in), optional supports can be added to minimize vibration, supporting complex automation layouts.
