Quick Detail

Description

The 31000-28-10-00-146-00-02 Proximity Probe Housing Assembly is a high-reliability solution for industrial automation applications, designed to house 3300 XL 8 mm Proximity Probes and provide external access for precise gap adjustments and probe maintenance. Constructed from glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers, the housing offers exceptional mechanical strength, corrosion resistance, and thermal stability. Stainless steel components, including AISI 303 exterior screws and AISI 304 retaining sleeves, enhance durability in demanding industrial environments. Rated Type 4X by CSA, the housing protects internal components against dust, water, and chemical exposure. It supports probe penetration options up to 14.6 inches (370 mm) and a standoff adapter length minimum of 1.5 inches (38 mm), while the neoprene O-ring ensures a secure seal. Housing impact strength is certified by BASEEFA, withstanding two 4 Joule (3.0 ft·lb) impacts at -39°C (-38°F) and 115°C (239°F). The 31000-28-10-00-146-00-02 assembly simplifies installation of radially mounted proximity probes for vibration, position, and Keyphasor measurements and is fully compliant with API 670 for externally mounted probe housings.

Applications

1. Radial Vibration Monitoring
Used in fluid-film bearing machines to house 3300 XL probes for radial vibration detection, enabling precise machinery health monitoring and predictive maintenance. The assembly allows field gap adjustments without halting operations.

2. Keyphasor Signal Acquisition
Facilitates collection of Keyphasor reference signals from rotating shafts, providing accurate phase and speed data essential for high-speed turbine and generator control.

3. Gap Adjustment in Active Machines
Allows operators to adjust probe-to-shaft gaps externally, reducing downtime and ensuring optimal linear range performance over 2 mm (80 mils).

4. Hazardous Area Installations
Compatible with intrinsically safe transducer systems and approved I.S. barriers, the housing is suitable for installation in Class I, Division 1 or ATEX/IECEx hazardous zones.

5. Corrosion-Resistant Mounting in Harsh Environments
The PPS thermoplastic and stainless steel construction withstands chemical exposure, high humidity, and extreme temperatures from -39°C to 115°C, ideal for petrochemical and offshore installations.

Specifications

Competitive Advantage

1. Superior Mechanical Strength
The PPS housing with conductive fibers offers exceptional rigidity, supporting stable probe alignment even under mechanical stress, minimizing measurement errors in vibration applications.

2. Certified Impact Resistance
BASEEFA-certified impact resistance ensures reliability at extreme temperatures, providing two separate 4 Joule impacts without structural compromise.

3. External Access for Maintenance
External housing design allows probe replacement and gap adjustment without disassembly of the machine, significantly reducing maintenance time and operational downtime.

4. Corrosion and Chemical Resistance
Glass-reinforced thermoplastic and stainless steel components provide superior resistance to corrosive industrial environments, extending service life in petrochemical and offshore facilities.

5. Compliance and Safety Standards
Fully API 670 compliant and CSA Type 4X certified, the assembly meets rigorous industrial and safety standards, ensuring suitability for hazardous and high-precision applications.
