Bently Nevada 21000-28-05-00-085-03-02 Proximity Probe Housing Assemblies

Description

The 21000-28-05-00-085-03-02 is a configured proximity probe housing assembly for the Bently Nevada 3300 XL monitoring system. This assembly provides environmental protection for the probe and includes the 3300 XL 8 mm transducer with selectable hazardous area approvals. This configuration features a 0.5 m (20 in) probe cable, 8.5 in (216 mm) probe penetration depth, and includes a cable seal grip fitting with grommets for secure lead routing. The assembly utilizes a 3/4-14 NPT mounting thread and is constructed with an aluminum body and 304 stainless steel sleeve to ensure mechanical integrity in industrial machinery environments.

This 21000 series assembly is designed for external mounting on machinery, conforming to industry standards for probe protection and cabling. The 085 probe penetration option and absence of a standoff adapter (Option 00) define the specific physical standoff and immersion depth for this unit. The cable seal grip (Option 03) provides a robust interface for the conduit or cabling system, while the 3/4-14 NPT mounting thread (Option 02) ensures compatibility with standard industrial mounting bosses.
