Quick Detail

Description

The 31000-28-05-20-110-00-02 Proximity Probe Housing Assembly is a precision-engineered solution designed for secure and reliable mounting of 3300 XL 8 mm Proximity Probes in industrial automation systems. Constructed from high-strength, corrosion-resistant PPS thermoplastic with conductive fibers, and complemented by AISI 304/303 stainless steel sleeves and screws, this housing provides robust mechanical protection for vibration and Keyphasor measurements. Certified Type 4X by CSA, the assembly withstands harsh environmental conditions, including extreme temperatures from -39°C to +115°C (-38°F to 239°F), and impacts up to 4 Joules, ensuring reliable long-term operation. The 3/4-14 NPT threaded mounting and 0.5 m probe cable allow easy installation, external gap adjustment, and probe replacement without disassembling machinery. With an 11 in probe penetration and 2.9 in standoff adapter, the housing ensures optimal positioning of the proximity probe for precise distance, position, and vibration monitoring. Fully compliant with API 670 standards, this housing assembly supports intrinsically safe applications when used with approved transducer systems and I.S. barriers, providing a reliable interface for automated condition monitoring in demanding industrial environments.

Applications

1. Radial Vibration Monitoring in Turbines
The housing allows radial mounting of 3300 XL probes on turbine shafts, enabling precise vibration measurements up to 2 mm linear range, critical for predictive maintenance and rotor health monitoring.

2. Gap Adjustment in Centrifugal Pumps
External access via the housing facilitates probe gap calibration without machine disassembly, maintaining measurement accuracy within ±2%, reducing downtime and improving operational efficiency.

3. Keyphasor Signal Acquisition for Rotating Machinery
Housing assemblies support the integration of Keyphasor measurements, enabling real-time phase and speed tracking, essential for automated control systems in compressors and generators.

4. Corrosive and High-Temperature Environments
PPS thermoplastic and stainless steel construction ensures performance in chemical, petrochemical, or offshore plants, maintaining Type 4X protection and consistent output under thermal cycling.

5. Intrinsically Safe Hazardous Area Monitoring
When combined with approved I.S. barriers and transducers, the housing assembly can be deployed in hazardous areas, providing reliable automation monitoring in Class I, Division 1 environments.
