Features:
- Through-Case Mounting for 3300 XL 8 mm Proximity Probes with External Access
- PPS Thermoplastic and Corrosion-Resistant Stainless Steel Construction
- API 670 Compliant with Multiple Approvals for Hazardous Area Operation
The 31000-28-05-40-040-02-02 functions as a Proximity Probe Housing Assembly for machinery protection systems, providing secure mounting of 3300 XL 8 mm proximity probes through the machine case.The 31000-28-05-40-040-02-02 enables external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine.
The 31000-28-05-40-040-02-02 provides essential housing functions for radially mounted transducers, and is a critical component of the vibration monitoring path, directly affecting the accuracy of the relative vibration signal when the machine casing is affixed to the bearing. One 31000-28-05-40-040-02-02 housing is required per radial probe mounting point.
For axial shaft position measurement applications, the 31000-28-05-40-040-02-02 is not recommended; housing 21022 is required instead. In addition to standard radial vibration monitoring, the 31000-28-05-40-040-02-02 configuration also supports intrinsically safe hazardous area operation when installed with an approved transducer system and appropriate I.S. barriers. The 31000-28-05-40-040-02-02 hazardous area installation executes compliance using the barrier specifications and external access design.
The 31000-28-05-40-040-02-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Radially Mounted Transducers: Primarily applied to house probes positioned perpendicular to a rotating shaft to measure radial vibration and absolute gap changes.
- Keyphasor Measurements: Safely secures probes configured to detect once-per-turn timing marks on a shaft, which provides essential phase angle data for balancing and diagnostic analysis.
- Severe Outdoor & Corrosive Environments: The non-corrosive PPS thermoplastic design makes it ideal for offshore oil platforms, chemical plants, and refineries where salt spray or chemical fumes would degrade aluminum enclosures.
- External Maintenance Access: Enables technicians to adjust or replace internal proximity probes from outside the machine casing, eliminating the need to shut down critical machinery or open primary gearboxes.
- Eddy Current Proximity Sensing: The enclosed 3300 XL probe utilizes an eddy current field to measure the exact displacement between the probe tip and the target surface without making physical contact.
- Dynamic Vibration Tracking: It accurately registers high-frequency dynamic movement, catching early mechanical faults such as shaft unbalance, misalignment, and fluid-film bearing wear.
- API 670 Machinery Protection: It fully supports compliance with API 670 standards, acting as the critical data collection point for automated emergency trip signals and preventative maintenance systems.
- Environmental Ingress Protection: Provides an IP66 and NEMA 4X rated seal, keeping out dust, moisture, and high-pressure water jets to maintain low-voltage signal integrity.
- Proximitor Sensor Integration: The internal 3300 XL 8 mm probe interfaces seamlessly with a standard 3300 XL Proximitor sensor via an approved extension cable.
- Plant Monitoring Architecture: The output signals from the Proximitor are fully compatible with Bently Nevada’s 3500 Machinery Protection System and the newer Orbit 60 platform.
- Target Material Calibration: The internal probe is factory-calibrated for standard AISI E4140 steel. Using it with other metallurgy requires specialized calibration adjustments.
- Physical Mounting Interchangeability: The 3/4-14 NPT mounting thread standardizes installation, allowing it to directly replace older metallic styles (such as the Bently Nevada 21000 aluminum housing) without retrofitting machine casings.
