Features:
- High-strength thermoplastic with excellent corrosion resistance for harsh environments.
- 1.5" standoff and 2.3" penetration for precise probe positioning.
- Fully compliant with API 670 Standard for externally mounted probe housings.
The 31000-00-00-15-023-01-02 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 31000-00-00-15-023-01-02 are made of corrosion-resistant stainless steel, ensuring long-term durability in demanding applications such as refineries, chemical plants, and offshore installations.
The 31000-00-00-15-023-01-02 provides precision adjustable mounting with a 1.5-inch standoff adapter (option C:15) and a 2.3-inch probe penetration (option D:023). 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 3.8 inches is well below the 12-inch threshold, so no additional sleeve support is required. The 31000-00-00-15-023-01-02 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 31000-00-00-15-023-01-02 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 31000-00-00-15-023-01-02 can be used in intrinsically safe hazardous area applications when installed with an approved transducer system and appropriate I.S. barriers. The 31000-00-00-15-023-01-02 is not an explosion-proof housing; for explosion-proof applications, use CA21000 or CA24701 housings. The 31000-00-00-15-023-01-02 is ideal for radial vibration and Keyphasor measurements on rotating machinery.
The 31000-00-00-15-023-01-02 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).

- Oil & Gas Upstream & Downstream: Mid-sized centrifugal pumps, screw compressors, and small gas turbines operating on offshore platforms, pipelines, and LNG plants.
- Power & Utility Infrastructure: Boiler feed pumps, forced draft (FD) and induced draft (ID) fans, and small hydro-turbine bearings.
- Petrochemical & Chemical Refining: Agitators, mixers, and blowers where continuous vibration monitoring is mandatory for plant safety.
- Marine & Maritime Propulsion: Main propulsion shaft bearings and auxiliary turbochargers on large vessels.
- Hazardous & Explosive Atmospheres: The -01 option grants global explosion-proof/flameproof certifications (ATEX, IECEx, and North American Class I, Division 1, Groups A, B, C, D). It contains any internal electrical spark, preventing the ignition of surrounding volatile gases.
- Aggressive Chemical Exposure: Constructed from heavy-duty, corrosion-resistant metals (typically aluminum or stainless steel) designed to resist hydrogen sulfide (H₂S), ammonia, hydrocarbon vapors, and salt spray in marine or coastal environments.
- Sub-Zero to High Heat Thermal Swings: Capable of operating in ambient temperatures ranging from -40°C to +100°C (-40°F to +212°F), shielding the probe from extreme seasonal weather and radiant machinery heat.
- Ingress Protection: Equipped with industrial-grade O-rings providing an IP66/NEMA 4X rating, completely locking out high-pressure water jets, ambient moisture, synthetic lubricants, and crude oil.
- Raw AC/DC Voltage Signal: The probe transmits a high-frequency RF signal through the housing’s flexible conduit (-02 option) to a Proximitor Sensor. The Proximitor converts this into a linear voltage signal (typically 200 mV/mil or 7.87 V/mm).
- What It Tracks: This signal continuously tracks micro-inch changes in Shaft Radial Vibration, Axial Thrust Position, and Rotational Speed (Keyphasor).
- Bently Nevada 3500/M System: The primary safety layer. The 3500 rack processes the signal against pre-set limits. If vibration exceeds a threshold, it acts as a Safety Instrumented System (SIS) to initiate an automatic emergency machinery trip (shutdown) via mechanical relays, saving millions in asset damage.
- DCS / PLC Integration: The data is shared via 4-20mA analog outputs or digital protocols (Modbus, Profibus, Ethernet/IP) to the plant's Distributed Control System (DCS) or Programmable Logic Controller (PLC) for real-time process control and operational dashboards.
