Bently Nevada 21000-16-05-20-033-00-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-20-033-00-02 is a Bently Nevada Proximity Probe Housing Assembly designed for industrial machinery condition monitoring. This specific configuration features a 3300 XL 8 mm proximity probe (Option A: 16) with a 0.5 meter (20 in) cable length (Option B: 05). It includes a 2.0 inch (51 mm) standoff adapter (Option C: 20) and a probe penetration depth of 3.3 inches (84 mm) (Option D: 033), providing precise positioning for non-contact shaft vibration and axial position measurements in critical rotating equipment.

This housing assembly is configured without fittings (Option E: 00) and utilizes a 3/4-14 NPT mounting thread (Option F: 02). It is constructed with an aluminum body and a 304 stainless steel sleeve to withstand industrial environmental conditions. The assembly provides mechanical protection for the probe and cable within the machine case, compliant with API 670 standards for externally mounted proximity probe housings.

Installation Guidelines

Ensure the housing is installed such that the probe is centered and perpendicular to the measured surface. Probe penetration adjustments can be made within the 13 mm (0.5 in) range provided by the housing design. For probe penetration lengths exceeding 300 mm (12 in), additional sleeve support is required to minimize vibration. Verify that the cable is routed away from high-temperature zones and potential abrasion points. Follow standard Bently Nevada 3300 XL system installation practices for proper gap voltage calibration.
