Features:
- High-strength thermoplastic with excellent corrosion resistance for harsh environments.
- 1.5" standoff and 3.5" penetration for precise probe positioning.
- Fully compliant with API 670 Standard for externally mounted probe housings.
The 31000-00-00-15-035-01-02 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 31000-00-00-15-035-01-02 are made of corrosion-resistant stainless steel, ensuring long-term durability in demanding applications such as refineries, chemical plants, and offshore installations.
The 31000-00-00-15-035-01-02 provides precision adjustable mounting with a 1.5-inch standoff adapter (option C:15) and a 3.5-inch probe penetration (option D:035). 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 5.0 inches is well below the 12-inch threshold, so no additional sleeve support is required. The 31000-00-00-15-035-01-02 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 31000-00-00-15-035-01-02 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 31000-00-00-15-035-01-02 can be used in intrinsically safe hazardous area applications when installed with an approved transducer system and appropriate I.S. barriers. The 31000-00-00-15-035-01-02 is not an explosion-proof housing; for explosion-proof applications, use CA21000 or CA24701 housings. The 31000-00-00-15-035-01-02 is ideal for radial vibration and Keyphasor measurements on rotating machinery.
The 31000-00-00-15-035-01-02 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 (Refineries & Petrochemical Plants): Used on high-speed turbomachinery like centrifugal compressors, steam turbines, gas turbines, and expansion turbines.
- Power Generation: Installed on large steam/gas turbine generators and cooling tower fans to monitor shaft vibration and position.
- Water & Wastewater / Heavy Industry: Applied to large industrial pumps, gearboxes, and electric motors.
- Hazardous & Corrosive Environments: The explosion-proof ratings allow it to be safely deployed in Class I, Division 1 (Groups A, B, C, D) or ATEX/IECEx Zone 1/2 explosive gas atmospheres, protecting the sensor from moisture, oil, and chemical exposure.
- Radial Vibration (Shaft Dynamic Motion): Measures the dynamic movement of the shaft relative to the bearing. High radial vibration indicates issues like machinery unbalance, misalignment, shaft bow, or fluid film bearing instability (oil whirl/whip).
- Axial Thrust Position (Shaft Axial Displacement): Monitors the axial movement of the shaft. This is a critical protection metric; excessive axial movement indicates thrust bearing degradation or failure, which can cause catastrophic internal rotor-to-stator contact.
- Keyphasor / Speed Measurement: Provides once-per-turn reference pulses to measure exact rotational speed and phase angle, crucial for advanced diagnostics like Bode, Polar, and cascade plots.
- Eccentricity: Measures the peak-to-peak bow of a turbine shaft at low turning-gear speeds before start-up to prevent thermal distortion damage.
- Mechanical Positioning & Gap Setting: The housing allows for external adjustment of the probe's gap relative to the shaft target. The probe must be gapped properly—typically to -10.0 Vdc (approx. 50 mils or 1.27 mm gap for a standard 3300 XL 8mm probe) using a digital voltmeter connected to the Proximitor sensor prior to tightening the locknuts.
- Conduit Sealing: Because this is an explosion-proof assembly, an approved explosion-proof conduit seal (sealing fitting) must be installed within 18 inches of the housing if required by local electrical codes (e.g., NEC/CEC).
- Moisture & Environmental Protection: Ensure the O-rings are greased and seated correctly during assembly to maintain the weatherproofing (IP66/NEMA 4X rating), preventing water ingress from shorting the coaxial cable connections.
