Quick Detail

Description

The 21000-34-10-20-062-04-02 Proximity Probe Housing Assembly is an all-metal external mounting solution specifically engineered for proximity probe installation in industrial automation and rotating machinery monitoring systems. Designed to accommodate the 3300 XL 8 mm proximity probe, this housing assembly ensures accurate probe positioning, mechanical stability, and long-term reliability in demanding operating environments.

With a 3/4-14 NPT mounting thread, 6.2 in probe penetration depth, and a 2.0 in standoff adapter, the 21000 series housing enables precise alignment for shaft vibration and displacement measurement. The aluminum housing body combined with a 304 stainless steel sleeve delivers excellent resistance to corrosion, vibration, and thermal stress. Supporting a 1.0 m probe cable, connector protection, and selectable hazardous area approvals, the 21000-34-10-20-062-04-02 proximity probe housing assembly complies with API 670 standards and is suitable for explosion-proof and intrinsically safe automation applications in power generation, oil and gas, and petrochemical facilities.

Applications

External Probe Installation on Turbines and Compressors

For large rotating machinery where internal mounting is restricted, the 6.2 in probe penetration allows accurate target access while keeping the probe externally mounted, improving serviceability and reducing downtime.

Hazardous Area Condition Monitoring

With support for CSA-approved explosion-proof configurations, this housing assembly is suitable for classified areas. The all-metal enclosure enhances safety in environments with flammable gases or vapors.

Shaft Vibration and Radial Position Measurement

When paired with a 3300 XL 8 mm proximity probe, the housing maintains stable probe-to-shaft spacing, supporting high-resolution displacement measurements typically required within a 2 mm linear range.

Retrofit of Existing Automation Monitoring Systems

The standardized 3/4-14 NPT interface enables direct replacement of older housings, minimizing mechanical rework during upgrades to modern machinery protection platforms.

API 670-Compliant Machinery Protection Systems

Power and process automation systems that require API 670-compliant probe mounting benefit from the defined geometry, certified materials, and consistent installation practices of the 21000 housing series.

Specifications

Competitive Advantage

Robust All-Metal Construction

The aluminum body and 304 stainless steel sleeve provide high structural strength and corrosion resistance, supporting continuous operation in high-vibration automation environments.

Extended Probe Penetration Capability

The 6.2 in penetration depth allows deeper access to measurement targets compared to shorter housings, improving installation flexibility on thick bearing housings.

Hazardous Area Certification Compatibility

Support for CSA Type 4 enclosure ratings and intrinsically safe probe options enables deployment in hazardous zones without additional protective enclosures.

Compliance with API 670 Standards

Designed to meet API 670 requirements, this housing assembly ensures regulatory compliance and consistent performance in critical machinery protection applications.

Flexible Sleeve and Support Options

For sleeve lengths exceeding 304 mm (12 in), optional supports can be added to reduce vibration effects, maintaining measurement accuracy in complex automation installations.
