Description

The 21000-16-05-00-074-04-02 is a robust proximity probe housing assembly designed for industrial machinery monitoring. This configuration specifies the 3300 XL 8 mm probe series (Option 16), a 0.5 m probe cable (Option 05), no standoff adapter (Option 00), a 7.4-inch probe penetration (Option 074), one 3/4-14 NPT plug (Option 04), and a 1/2-14 BSP mounting thread (Option 02). As part of the Bently Nevada 21000 series, this housing is engineered with an aluminum body and a 304 stainless steel sleeve to provide secure, protective mounting for eddy-current proximity probes. It complies with API 670 standards for externally mounted housings. This unit is intended for applications where reliable shaft vibration and axial position measurement are required in heavy industrial environments such as power generation and petrochemical facilities.

Installation Guidelines

Ensure the probe lead is longer than the sleeve length during installation.
For probe penetration lengths (C+D) exceeding 300 mm (12 in), install additional sleeve support to minimize vibration-induced resonance.
When probe penetration is between 1.0 and 2.0 inches, counter-boring the machine case may be required to reduce side-view or rear-view effects.
Use appropriate sealant and thread care for NPT/BSP connections to maintain environmental integrity.
