Bently Nevada 21000-16-05-00-135-03-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-00-135-03-02 is an aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This configuration includes a 3300 XL 8mm probe (Option 16), a 0.5 m probe cable (Option 05), and a 3/4-14 NPT mounting thread (Option 02) for secure installation in industrial machinery monitoring applications. The assembly provides environmental protection for the probe and cabling while ensuring the precise, rigid mounting required for accurate shaft vibration and axial position measurement.

This unit features no standoff adapter (Option 00) and a probe penetration depth of 13.5 inches (Option 135). It is equipped with one cable seal grip with grommets (Option 03) for flexible cable entry management. Compliant with American Petroleum Institute (API) 670 standards, this all-metal housing assembly is built for durability in harsh industrial environments, offering reliable protection for critical rotating equipment.

Installation Guidelines

• Ensure the probe lead is longer than the sleeve length during installation.
• For probe penetration lengths (Option C + Option D) greater than 300 mm (12 in), install additional sleeve support near the probe to prevent resonance.
• When using the cable seal grip (Option E:03), ensure grommets are correctly sized for the cable diameter to maintain environmental seal integrity.
• Avoid exposing 3300 XL probes to temperatures below -34 degC (-30 degF) to prevent pressure seal damage.

Compliance and Certifications

• RoHS: Compliant with EU Directive 2011/65/EU
• Industry Standards: API 670 Compliant
