The Bently Nevada 21000 and 24701 are all-metal Proximity Probe Housing Assemblies designed for external mounting of proximity probes, widely used to protect probes in industrial environments. While they share similar functional components—a dome cover, threaded ports, probe sleeve, and O-rings—their primary differences lie in material construction, weight, and environmental suitability.
Purpose: Both allow external mounting of proximity probes (3300 XL 8mm, 11mm, and 3300 NSV probes) for machinery monitoring.
Explosion Protection: Both are rated for explosion-proof applications in hazardous areas and are CSA Certified as Type 4 enclosures.
Compliance: Both meet American Petroleum Institute (API) 670 standards
