Bently Nevada 21000-28-05-15-012-04-02 Proximity Probe Housing Assemblies

Overview

The Bently Nevada 21000‑28‑05‑15‑012‑04‑02 proximity probe housing assembly is designed for externally mounted proximity probes used in radial vibration, shaft position, and Keyphasor signal measurement. As part of the 21000‑28 series, this housing provides a stable, sealed, and mechanically aligned interface for 3300‑series proximity transducers installed through the machine case.

Functional Characteristics

This housing assembly supports forward‑mount probe configurations and includes a precision‑machined stainless‑steel sleeve that maintains probe alignment and insertion depth. The design allows technicians to access the probe and extension cable externally, enabling gap adjustments or probe replacement without opening the machine casing.

The 21000‑28‑05‑15‑012‑04‑02 uses corrosion‑resistant materials suitable for high‑temperature and oil‑contaminated environments. Conduit ports support flexible cable routing, while internal sealing components protect the probe from moisture, debris, and mechanical vibration.
