Features:

  • High-strength thermoplastic with excellent corrosion resistance for harsh environments.
  • 1.5" standoff and 5.1" penetration for precise probe positioning.
  • Fully compliant with API 670 Standard for externally mounted probe housings.
The 31000-00-00-15-051-01-02 features a housing made of polyphenylene sulfide (PPS), an advanced, high-strength thermoplastic with excellent corrosion resistance. This material is ideal for harsh industrial environments where chemical exposure or moisture could damage standard metal housings. The PPS construction provides reliable mechanical and environmental protection for the proximity probe while maintaining a lightweight profile. All other elements of the 31000-00-00-15-051-01-02 are made of corrosion-resistant stainless steel, ensuring long-term durability in demanding applications such as refineries, chemical plants, and offshore installations.

The 31000-00-00-15-051-01-02 provides precision adjustable mounting with a 1.5-inch standoff adapter (option C:15) and a 5.1-inch probe penetration (option D:051). The standoff adapter positions the housing at the optimal distance from the machine case, while the probe penetration determines how far the probe extends toward the target surface. The "C" plus "D" dimension of 6.6 inches is well below the 12-inch threshold, so no additional sleeve support is required. The 31000-00-00-15-051-01-02 features a 3/4-14 NPT mounting thread (option F:02) and one 3/4-14 NPT fitting with two plugs (option E:01).

The 31000-00-00-15-051-01-02 is fully compliant with API 670 Standard for externally mounted proximity probe housings, ensuring it meets industry requirements for mechanical configuration, accuracy, and reliability. The 31000-00-00-15-051-01-02 can be used in intrinsically safe hazardous area applications when installed with an approved transducer system and appropriate I.S. barriers. The 31000-00-00-15-051-01-02 is not an explosion-proof housing; for explosion-proof applications, use CA21000 or CA24701 housings. The 31000-00-00-15-051-01-02 is ideal for radial vibration and Keyphasor measurements on rotating machinery.

The 31000-00-00-15-051-01-02 Bently Nevada PPS Probe Housing may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Functional Safety (SIL Compliance): When used as part of a complete Bently Nevada loop (Probe + Proximitor + 3500 Monitor), this assembly complies with IEC 61508 standards up to SIL 2 (Safety Integrity Level), allowing it to be used in formal Emergency Shutdown (ESD) or Safety Instrumented Systems (SIS).
Description
The Bently Nevada 31000-00-00-15-051-01-02 is a PPS (polyphenylene sulfide) proximity probe housing assembly designed for externally mounting proximity probes through the machine case. This housing provides mechanical and environmental protection for the probe while allowing external access for gap adjustment and probe replacement without machine disassembly. The 31000-00-00-15-051-01-02 is compatible with radially mounted transducers for vibration and Keyphasor measurements. 

The Bently Nevada 31000-00-00-15-051-01-02 has no probe included (option A:00) and no probe cable (option B:00), with a 1.5-inch standoff adapter (option C:15) and a 5.1-inch probe penetration (option D:051). The 31000-00-00-15-051-01-02 features one 3/4-14 NPT fitting with two plugs (option E:01) and a 3/4-14 NPT mounting thread (option F:02).

The Bently Nevada 31000-00-00-15-051-01-02 is constructed from high-strength PPS thermoplastic with excellent corrosion resistance, with all other elements made of corrosion-resistant stainless steel. The 31000-00-00-15-051-01-02's standoff plus penetration dimension (C+D) is 6.6 inches (167.6mm), which is less than 12 inches, so no additional sleeve support is required.

The Bently Nevada 31000-00-00-15-051-01-02 can be used in intrinsically safe hazardous area applications when installed with an approved transducer system and appropriate I.S. barriers. The 31000-00-00-15-051-01-02 is not an explosion-proof housing; for explosion-proof applications, use CA21000 or CA24701.
