Features:
- Interface Between the Proximity Probe and 3500 Monitoring System Backplane
- Integrates 3300 XL 8mm Probe Technology with Explosion-Proof Housing Protection
- Functions in Conjunction with Bently Nevada Machinery Protection and Condition Monitoring Systems
The Bently Nevada 21000-28-05-00-47-01-02 Proximity Probe Housing Assembly serves as a critical external mounting solution for proximity probes within industrial monitoring infrastructures, providing robust physical protection and reliable signal transmission for vibration and position measurement applications. The 21000-28-05-00-47-01-02 continuously safeguards the internal 3300 XL 8mm proximity probe while maintaining precise detection capabilities through its 4.7 inch probe penetration depth, distributing accurate shaft position and vibration data through the probe cable to support continuous machinery health monitoring.
The 21000-28-05-00-47-01-02 provides essential probe protection functions common to demanding industrial applications, and is a critical component of the measurement path, directly affecting the proper, accurate operation of the overall condition monitoring system. One 21000-28-05-00-47-01-02 housing assembly is required per probe installation point depending on the specific machinery monitoring requirements. The 21000-28-05-00-47-01-02 occupies a dedicated external mounting position on the machinery casing and is always installed with its 3/4-14 NPT mounting thread securely fitted to the designated port.
For hazardous area applications, the 21000-28-05-00-47-01-02 requires proper installation of its explosion-proof fittings to maintain safety ratings. In addition to standard probe housing protection, the certified configuration also performs environmental sealing. The 21000-28-05-00-47-01-02 dual fitting design executes secure conduit connections using the 3/4-14 NPT explosion-proof fitting and plug specified in the housing assembly options. Using this method, the 21000-28-05-00-47-01-02 continually maintains the integrity of the internal probe environment. If the system detects that the housing seal is compromised or requires maintenance, the modular design allows for straightforward inspection and replacement of O-rings and thread seals while preserving the explosion-proof rating.
The 21000-28-05-00-47-01-02 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).

- External Machine Mounting: Deployed to mount proximity probes externally on critical industrial machinery. It is fully compliant with the API 670 Standard for vibration, axial position, and timing measurements.
- Rotating Machinery Monitoring: Used on large-scale rotating equipment such as steam turbines, gas turbines, compressors, pumps, and gearboxes to monitor shaft vibration and position.
- Online Adjustments: Ideal for applications requiring sensor maintenance, calibration, or replacement during operation, eliminating the need for costly machine shutdowns.
- Temperature Range: The probe assembly operates efficiently in extreme temperatures, supporting a range from -51 °C to +177 °C (-60 °F to +351 °F).
- Environmental Sealing: Certified as a CSA Type 4 / NEMA 4 enclosure, ensuring high resistance against moisture, dust, and water ingress.
- Material Composition: Features a lightweight aluminum body paired with a durable 304 stainless steel probe sleeve, balancing physical strength with reduced structural weight.
- Hazardous Area Readiness: Built for volatile environments with official CSA and BASEEFA/CENELEC approvals. It is rated explosion-proof and intrinsically safe for Class I (Div 1 & 2, Groups C & D) and Class II (Div 1 & 2, Groups E, F, & G) hazardous locations.
- Mechanical Protection: The rugged dome cover and body shield internal reverse-mount proximity probes from mechanical impacts, high-velocity oil splashes, and external debris.
- Signal Integrity: Prevents environmental noise and moisture from disrupting the low-voltage eddy current signals, ensuring consistent, high-fidelity monitoring data for machine protection systems.
- Resonance Mitigation: The system accommodates precise sleeve lengths. Long sleeves (greater than 12 inches) feature built-in structural design considerations to accept additional supports or oil seals, preventing mechanical resonance from causing measurement distortion.
