Quick Detail

Description

The 31000-00-00-00-031-01-02 English Proximity Probe Housing Assembly is a high-performance solution designed for industrial automation applications requiring precise and reliable vibration or Keyphasor measurements. Engineered for mounting proximity probes through machine casings, this housing assembly supports radially mounted transducers and facilitates external access to probes and extension cables, enabling rapid gap adjustments or probe replacement without disassembling critical machinery. Constructed from glass-reinforced polyphenylene sulfide (PPS) thermoplastic embedded with conductive fibers, the housing delivers superior strength, chemical resistance, and thermal stability. Stainless steel components, including AISI 304 sleeve and retaining chain, and AISI 303 exterior screws, ensure exceptional corrosion resistance. The assembly includes one 3/4-14 NPT fitting and two plugs, supports a probe penetration depth of 3.1 inches, and provides CSA-certified Type 4X protection. Its impact strength is verified by BASEEFA, sustaining two separate 4 Joule impacts at extreme temperatures ranging from -39°C to 115°C. The 31000-00-00-00-031-01-02 fully complies with API 670 standards and, when paired with approved transducer systems and intrinsic safety barriers, is suitable for hazardous area installations. Recommended retaining nut torque is 29.4 N·m (260 in·lb).

Applications

Rotating Machinery Vibration Monitoring

Designed for use in turbines, compressors, and pumps, the housing assembly allows precise placement of 3300 XL Proximity Probes to measure shaft vibration, improving predictive maintenance and reducing unexpected downtime.

Keyphasor Measurement in Steam and Gas Turbines

Supports radially mounted transducers to capture rotor position signals, enhancing phase reference accuracy for speed and vibration analysis in turbine control systems.

Hazardous Area Instrumentation

Certified for intrinsically safe operation when combined with proper I.S. barriers, allowing installation in refinery, petrochemical, and offshore environments where explosion-proof standards are required.

High-Temperature and Cold-Climate Environments

Impact-tested at temperatures from -39°C to 115°C, enabling reliable performance in extreme operating conditions without degradation of housing strength or probe alignment.

Retrofit and Maintenance-Friendly Designs

External access to probes and cables allows quick replacement or gap adjustment during scheduled maintenance, reducing downtime and enhancing operational efficiency in automated industrial plants.
