Description

Bently Nevada 21000-28-05-20-037-04-02 Proximity Probe Housing Assembly

The assembly functions as an explosion-proof, API 670 compliant external protective enclosure engineered for rugged machinery asset protection. Featuring a lightweight aluminum main body matched with an industrial-grade 304 stainless steel protective sleeve, this configuration safely encapsulates an integrated 3300 XL 8mm reverse-mount proximity probe for precise eddy current displacement measurements in volatile settings.

Quick Installation Guide

  • Thread the 2.0-inch standoff adapter assembly safely into the machine casing wall using the 3/4-14 NPT mounting option.
  • Verify the 1.1 kg mechanical mass is appropriately supported before finalizing rigid conduit connections to the threaded ports.
  • Examine the factory Viton O-rings and thread seals during assembly to confirm they are uncompromised and fully seated for Type 4 ingress integrity.

Technical FAQs

Q1: What mechanical purpose does the 20-standoff adapter option fulfill?
A1: The 2.0-inch standoff acts as an external spacing block, keeping the main aluminum body clear of dense thermal insulation blankets or tight mechanical constraints on the machinery frame.

Q2: Why is the combination of aluminum and stainless steel used in the 21000 design?
A2: This mixed design limits the hardware base weight to a highly manageable 1.1 kg via the cast dome shell, while maintaining an extremely rigid 304 stainless steel path down the immersion sleeve where high shear strains can occur.

Q3: Is this global 21000 housing certified for refinery fields in Europe?
A3: Yes, standard 21000 serial logs are designated for international end-user deployment outside North America and carry appropriate global compliance foundations that align perfectly with API 670 criteria.
