• Probe Penetration: 4.6 in
• Mounting Thread: 3/4-14 NPT
• Material: Aluminum body with 304 stainless steel sleeve
• Weight: 1.1 kg (2.4 lb) typical, without fittings
• Maximum Dimension (C+D): 32.9 in (83.5 cm)

This assembly is CSA certified as Type 4 enclosure and complies with API 670 standard for externally mounted proximity probe housings.

Applications and Use Cases

In petrochemical plants and refineries, the 21000-16-10-00-046-03-02 excels at monitoring shaft vibration and position. It is ideal for compressors, turbines, and pumps where hazardous area approvals are required. The explosion-proof rating makes it suitable for Zone 1 and Zone 2 environments. Additionally, its robust construction reduces maintenance needs and extends service life in harsh conditions.

Installation and Setup

Mount the housing using the 3/4-14 NPT thread into a compatible conduit or standoff adapter. Ensure the probe penetration of 4.6 in is set correctly for optimal gap voltage. Use the provided cable seal grip with appropriate grommet for cable sizes between 1/8 and 3/8 inches. Tighten fittings to prevent leakage in hazardous areas. Always follow Bently Nevada's installation manual for precise positioning.

Maintenance and Reliability

Regularly inspect the O-rings and thread seal for wear to maintain explosion-proof integrity. Clean the dome cover and body with a soft cloth; avoid solvents that may damage seals. Verify cable connections periodically to prevent signal loss. The aluminum body with stainless steel sleeve resists corrosion, reducing long-term replacement costs. Following these steps ensures reliable operation and extends the assembly's lifespan.

Compatibility and Integration

The 21000-16-10-00-046-03-02 integrates with Bently Nevada monitoring systems and third-party vibration analyzers. It is compatible with 3300 XL 8 mm proximity probes and standard conduit fittings. The CSA Type 4 enclosure allows outdoor installation. For intrinsically safe applications, pair with approved proximity probes and barriers. Refer to the datasheet for system compatibility details.
