Bently Nevada 21000-16-10-00-067-04-02 Proximity Probe Housing Assembly

Description

The 21000-16-10-00-067-04-02 is an aluminum proximity probe housing assembly designed to externally mount proximity probes for vibration and position monitoring applications. This specific configuration features a 3300 XL 8 mm proximity probe (Option 16) with a 1.0 meter cable (Option 10) and a 6.7 inch probe penetration length (Option 067). It includes no standoff adapter (Option 00) and is equipped with a 3/4-14 NPT plug fitting (Option 04) for reliable port sealing.

This assembly provides a secure, all-metal environment for probe installation in industrial rotating machinery. The housing protects the transducer from harsh process conditions and ensures the probe remains accurately positioned relative to the target surface. The aluminum construction balances durability with weight, making it a standard choice for API 670 compliant machinery protection systems.

Features

• 3300 XL 8 mm probe compatibility for eddy-current displacement measurement
• 1.0 m cable length to suit local junction box or field interface requirements
• 6.7 inch probe penetration depth for tailored mounting distance
• Aluminum body providing lightweight yet robust machinery protection
• 3/4-14 NPT plug included for effective conduit port closure
• 3/4-14 NPT mounting thread for standardized installation in machine cases

Applications

• Externally mounted proximity probe protection for gas and steam turbines
• Centrifugal compressor shaft vibration monitoring
• Axial position measurement in harsh industrial environments
• Applications requiring API 670 compliant proximity probe mounting

Installation Guidelines

Ensure the probe penetration length (Option D) is correctly calculated to maintain the required nominal gap between the probe tip and the target. For installations where probe penetration exceeds 300 mm (12 inches), add sleeve support near the probe tip to minimize vibration and prevent resonance. Ensure all threaded NPT connections are properly sealed using compatible thread sealant to maintain the integrity of the explosion-proof rating where required. Verify that the cable is routed in a way that prevents mechanical stress on the probe lead.

Compliance and Certifications

The 21000 series housings are compliant with API 670 standards for externally mounted proximity probe housings. When installed according to manufacturer documentation, they are suitable for use in various industrial environments. Please consult the product datasheet and 108M1756 Approvals Quick Reference Guide for specific hazardous area certifications applicable to your region.
