Bently Nevada 21000-16-05-00-077-03-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-00-077-03-02 is a specific configuration of the Bently Nevada 21000 series aluminum proximity probe housing assembly, designed for the external mounting of 3300 XL 8 mm proximity transducers. This assembly provides a robust, weather-resistant enclosure for the probe and its connector, ensuring mechanical protection in industrial environments. This unit features a 0.5 m (20 in) probe cable (Option 05), no standoff adapter (Option 00), and a 7.7 in probe penetration depth (Option 077).

Engineered to comply with the American Petroleum Institute (API) 670 Standard, this housing assembly serves as a critical component for reliable shaft vibration and position monitoring. The 16 configuration code indicates compatibility with the 3300 XL 8 mm probe series. The assembly includes a cable seal grip (Option 03) to accommodate varying cable diameters and a 1-11 1/2 NPT mounting thread (Option 02) for secure attachment to machine cases.

Features

• Probe Compatibility: Configured for 3300 XL 8 mm proximity probes (Option 16).
• Probe Cable Length: Includes 0.5 m (20 in) lead length (Option 05).
• Probe Penetration: 7.7 inch (195.6 mm) penetration depth (Option 077).
• Housing Material: Aluminum body with 304 stainless steel sleeve for durability.
• Fittings: Equipped with one cable seal grip (Option 03) for secure cable entry.
• Mounting Thread: 1-11 1/2 NPT mounting thread (Option 02) featuring increased thread count for structural stiffness.
• API Compliance: Designed to meet API 670 standards for externally mounted probe housings.

Applications

Used primarily in power generation, petrochemical, and oil and gas industries for the external mounting of proximity probes on rotating machinery such as turbines, compressors, pumps, and motors. It is suitable for applications where environmental protection of the probe and connector system is required to maintain measurement integrity.

Installation Guidelines

Ensure the probe lead is longer than the internal sleeve to prevent cable strain. For penetration lengths (C+D) exceeding 300 mm (12 in), additional sleeve support is mandatory to mitigate resonance. Use the provided cable seal grip (Option 03) to ensure a proper seal against moisture and contaminants. Ensure the NPT mounting threads are properly sealed using thread sealant compatible with the environment.

Compliance and Certifications

The 21000 housing assembly is compliant with RoHS Directive 2011/65/EU. For hazardous area applications, ensure specific installation requirements are met per the system datasheet and local electrical codes. The 21000 series is compatible with CSA-rated installations when ordered with appropriate components.
