The Bently Nevada 21000-28-05-00-070-01-02 Proximity Probe HousingAssemblies is part of an all‑metal suite of proximity probe housing assemblies, crafted for external mounting in hazardous industrial environments. You can choose either the 21000 aluminum or the 24701 stainless‑steel housing; both are CSA explosion‑proof, Type 4 rated, and fully compliant with API 670 for reliable machinery protection. The aluminum body, complemented by a 304 stainless sleeve, ensures rugged performance under extreme temperatures from –51 °C to +177 °C.

This specific model, 21000-28-05-00-070-01-02 Bently Nevada, includes a 3300 XL 8 mm reverse‑mount proximity probe (“28”), a 0.5 m cable (“05”), no standoff adapter (“00”), and a 7.0‑inch sleeve (“070”) for deep‑penetration monitoring. It also comes factory‑fitted with one explosion‑proof fitting and plug (“01”), and standard 3/4‑14 NPT mounting threads (“02”), facilitating secure installation.

Like all 21000 assemblies, the 21000-28-05-00-070-01-02 Proximity Probe HousingAssemblies features a screw‑in dome cover, threaded conduit ports, O‑rings, thread seals, and offers optional conduit fittings—plus flexibility to adapt standoff adapters—enabling field‑serviceable access for probe replacement or gap adjustments without dismantling machinery.

Weighing approximately 1.1 kg without fittings, the Proximity Probe 21000-28-05-00-070-01-02 is built in the USA, ships in roughly 12–18 weeks with a 12‑month factory warranty, and is ready to be deployed for precision vibration and position monitoring in extreme environments .
