Features:
- Explosion-Proof Proximity Probe Housing Protects 3300 XL 8 mm Probes In Hazardous Areas
- Aluminum Body With Stainless Steel Sleeve Ensures Durable And Reliable Installation
- Flexible Design Supports Multiple Mounting Options And Standard 3/4-14 NPT Threads
The Bently Nevada 21000-28-10-00-217-04-02 Proximity Probe Housing Assembly is engineered to provide secure external mounting for 3300 XL 8 mm probes, addressing the need for precise shaft position and vibration monitoring in harsh and potentially explosive industrial environments. Its explosion-proof design ensures safe operation while protecting sensitive probes from moisture, dust, and mechanical impact.
This housing assembly is ideal for use on turbines, compressors, pumps, generators, and electric motors. With a probe cable length of 1.0 m (39 in) and compatibility with optional standoff adapters, the 21000-28-10-00-217-04-02 allows flexible installation to accommodate various machinery layouts. The aluminum body combined with a 304 stainless steel sleeve offers robust durability while keeping the assembly lightweight and easy to handle.
Compared with similar Bently Nevada housing assemblies, such as the 24701 stainless steel model, the 21000-28-10-00-217-04-02 provides an optimal balance between strength, weight, and installation flexibility. Its integrated dome cover, threaded ports for conduit, O-rings, and optional conduit fittings make it a complete solution for externally mounting proximity probes while maintaining CSA-approved explosion-proof protection in hazardous areas.
The 21000-28-10-00-217-04-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Linear Range: 80 mils (2.0 mm), standard sensitivity 200 mV/mil (7.87 V/mm).
- Frequency Response: 0 Hz to 10 kHz, capable of capturing the full range of signals from static displacement to high-frequency vibration.
- Interchangeability: Designed to conform to highly standardized electrical characteristics, ensuring extremely high interchangeability of probes with the same system length (5m or 9m).
- Resolution: Micrometer-level measurement accuracy, effectively identifying extremely small mechanical anomalies within bearings.
- Radial Vibration: Mounted in pairs (X-Y) on sliding bearings to monitor shaft trajectory analysis and operational stability.
- Axial Displacement: Monitors the longitudinal movement of the shaft relative to the thrust bearing as a critical shutdown protection parameter.
- Keyphasor: Mounted in the keyway of the shaft, providing a voltage pulse per revolution for speed measurement and phase analysis.
- Core Equipment: Widely used in steam turbines, centrifugal compressors, large motors, and pumps in operation worldwide.
- Operating Temperature: The probe and cable withstand temperatures from -34°C to +177°C (-30°F to +350°F).
- Sealing: Hermetically sealed design with highly chemical-resistant polyphenylene sulfide (PPS) material at the tips.
- Pressure Resistance: The probe head is designed to withstand oil pressure inside the bearing housing, typically up to 50 psi.
- Hazardous Area Certification: Compliant with ATEX/IECEx and CSA standards, suitable for Zone 0 and Zone 1 environments involving flammable and explosive materials such as those found in the petroleum and petrochemical industries.
