Features:
- Designed with CSA-certified explosion-proof protection and CSA Type 4 enclosure compliance for hazardous industrial environments.
- Combines an aluminum body with a 304 stainless steel sleeve for dependable mechanical protection and structural stability.
- Supplied with a 3300 XL 8 mm reverse mount probe, threaded conduit ports, and 3/4-14 NPT mounting connection for externally mounted installations.
Bently Nevada 21000-16-05-00-050-04-02 is designed to support externally mounted proximity probe installations used in machinery monitoring systems. The assembly combines a metal housing structure with integrated conduit connection capability for organized installation layouts. Its aluminum housing body and stainless steel sleeve help provide dependable mechanical support in industrial environments. The included 3300 XL 8 mm reverse mount probe allows the assembly to function as a complete mounting solution. CSA approvals and API 670 compliance further support its use in regulated industrial applications.
Bently Nevada 21000-16-05-00-050-04-02 includes a 0.5 m probe cable and a 5.0 inch probe penetration dimension to accommodate defined installation requirements. The unit uses a 3/4-14 NPT mounting thread together with one 3/4-14 NPT plug fitting for conduit integration. Internal assembly components include O-rings, threaded conduit ports, a thread seal, and a dome cover that screws into the housing body. These elements help maintain a protected internal probe arrangement while supporting external mounting configurations. The housing can also be configured with optional fittings depending on installation requirements.
The 21000 series housing arrangement used in Bently Nevada 21000-16-05-00-050-04-02 remains suitable for applications requiring explosion-proof externally mounted probe protection. Bently Nevada notes that longer sleeve lengths above 304 mm require additional support to reduce vibration associated with unsupported sleeves. Optional accessories such as probe supports and oil seals are available for installations extending through inner bearing housings. The assembly also supports intrinsically safe application requirements when hazardous area approved probes are ordered with compatible housing configurations. Its overall design focuses on maintaining secure probe positioning and structured installation in industrial monitoring systems.
The 21000-16-05-00-050-04-02 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).

- Rotating Machinery Monitoring: Primarily used for monitoring radial vibration or axial position in equipment such as motors, pumps, compressors, and small steam turbines, especially widely applied in conventional thermal power plants and pumping stations.
- Convenient External Installation: When the probe cannot be installed inside the machine casing, this component allows for external probe mounting. The probe is inserted into the monitoring point via a sleeve, and the clearance can be adjusted without disassembling the equipment.
- Hazardous Environment Deployment: Combined with explosion-proof options, it is suitable for industrial sites in oil and gas industries requiring North American CSA-certified explosion-proof ratings.
- Standardized System Integration: Fully compliant with API 670 standards, it is the standard industrial-grade packaged solution for external probes in critical asset protection systems.
- Equipment Fault Early Warning: By capturing probe signals in real time, technicians can analyze changes in shaft trajectory to identify faults such as oil film eddying at an early stage. Case studies show that this system successfully provided fault warnings 14 days in advance, preventing unplanned load shedding.
- Signal Integrity Verification: Through the component's built-in probe clearance adjustment function, maintenance personnel can verify static voltage without disassembling the machine, ensuring the accuracy and linearity of the monitoring signal.
- Eliminating Mechanical Resonance: For extra-long housings (over 12 inches), the enclosure supports the installation of dedicated supports (such as P/N 37948-01) to prevent spurious vibration signals that could distort diagnostic data.
- Isolating External Interference: The all-metal aluminum enclosure provides excellent electromagnetic shielding, preventing interference from field electrical noise on micron-level vibration monitoring signals.
- Explosion-Proof Safety Standards: The 21000 Series is CSA certified, with ratings covering hazardous areas such as Class I Div 1 & 2 (Groups C, D), meeting the most stringent safety requirements of the petrochemical industry.
- API 670 Specification: Fully compliant with all structural and performance requirements of the American Petroleum Institute's API 670 standard for "externally mounted probe housings," making it a globally recognized compliant choice in industrial applications.
- Environmental Protection Rating: The enclosure is certified to CSA Type 4 protection rating (similar to IP66), ensuring long-term reliable operation in dusty, splashing, or mildly corrosive industrial environments.
- Certification Compliance: This component requires that the certification options for the probe, cable, and housing be compatible (e.g., all are explosion-proof) to ensure that the entire monitoring loop maintains explosion-proof integrity in a legal and engineering sense.
