Proximity Probe Housing Assembly
A configurable 21000 aluminum proximity probe housing assembly for externally mounted proximity probes. This configuration combines a 3300 XL 8 mm probe, 0.5 m probe cable, no standoff adapter, 3.5-inch probe penetration, and 3/4-14 NPT mounting.
Selectable hazardous-area approvals.
0.5 m / 20 in probe cable.
No standoff adapter.
3.5 in nominal penetration.
One 3/4-14 NPT explosion-proof fitting and one 3/4-14 NPT plug.
3/4-14 NPT mounting thread.
The 21000 assembly uses an aluminum body with a 304 stainless steel sleeve. The assembly is intended for externally mounted proximity probes.
The official specifications list this operating and storage range for the 3300 XL 8 mm probe.
The 21000 housing is approximately 1.1 kg without fittings.
The 21000 series is designed to externally mount proximity probes used in machinery monitoring installations. The housing provides a defined mechanical enclosure for the probe, cable routing, penetration and mounting arrangement.
The 3300 XL 8 mm probe configuration is associated with proximity measurement systems used for machinery protection and condition monitoring. Bently Nevada identifies proximity systems as part of monitoring solutions for rotating machinery.
When the selected probe penetration plus standoff length exceeds 300 mm (12 in), the official specification requires additional sleeve support near the probe to reduce resonance.
For penetration lengths between 1.0 and 2.0 inches, the machine case may require counter-boring to reduce probe side-view or rear-view effects.
When a Proximitor sensor and extension cable are ordered with the housing, the probe should have matching approval options for the intended installation.
