Bently Nevada 21000-16-05-00-073-04-02 Proximity Probe Housing Assembly

Description

The 21000-16-05-00-073-04-02 is a robust proximity probe housing assembly designed for industrial machinery protection, featuring a 3300 XL 8 mm proximity probe configuration. This assembly provides environmental protection and secure mounting for proximity probes, utilizing an aluminum body construction with a stainless steel sleeve to ensure durability in demanding operational conditions. This specific variant includes a 0.5 m cable length, a 7.3-inch probe penetration depth (Option 073), and a 3/4-14 NPT mounting thread with a plug fitting.

Engineered for compliance with API 670 standards, this housing protects the transducer probe against physical damage while maintaining the precise alignment required for shaft vibration and axial position monitoring. The 21000 series is ideal for use in hazardous areas when ordered with appropriate options, providing a reliable interface between the machine case and the monitoring system. The assembly includes specialized fittings for conduit entry, ensuring a sealed environment for the probe lead and connector system.

Installation Guidelines

Ensure the housing is installed using a 3/4-14 NPT thread connection to the machine case. For probe penetration depths greater than 300 mm (12 in), auxiliary sleeve support is required to mitigate vibration-induced resonance. Ensure all fittings are properly torqued to maintain environmental integrity. If the probe penetration is between 1.0 and 2.0 inches, counter-boring the machine case may be necessary to minimize side-view effects on the probe output.
