Configured for proximity probe mechanical mounting and signal protection in Bently Nevada 21000 Series platforms, the Bently Nevada 21000-16-05-00-066-03-02 (21000 Proximity Probe Housing Assemblies) provides direct physical installation support for 3300 XL 8 mm proximity probe systems.

Model Configuration Details

The 21000-16-05-00-066-03-02 Proximity Probe Housing Assembly is designed to provide a protected mounting arrangement for Bently Nevada proximity probes. The assembly configuration supports installation of one 3300 XL 8 mm probe with a 0.5 m (20 in) housing length.

The model includes NPT mounting components and cable sealing accessories for field installation. The assembly provides mechanical protection and maintains probe positioning within vibration and displacement monitoring applications.

Hardware Specifications

Eddy-Current Probe Installation and Mechanical Protection

The 21000 housing assembly supports proper eddy-current probe installation by maintaining fixed mechanical positioning and protecting the probe interface from external installation conditions.

Correct probe scaling and gap voltage validation depend on accurate mechanical alignment between the probe tip and the monitored shaft surface. The housing assembly provides the mounting structure required for maintaining probe placement during machine operation.

The assembly configuration includes sealing components that help maintain cable entry protection and reduce mechanical movement at the probe connection point.
