Description
The 21000-28-05-00-085-03-02 is a fully integrated, safety-certified housing assembly designed to enable reliable machinery monitoring within explosive atmospheres. This specific configuration is engineered to accommodate a 3300 XL series 8 mm proximity probe, which is factory-mounted and features multiple agency approvals for hazardous locations. 

This assembly, identified as 21000-28-05-00-085-03-02, is constructed from durable materials to withstand harsh conditions. The main housing body is made of aluminum for a balance of strength and weight, while the critical probe sleeve is fabricated from corrosion-resistant 304 stainless steel to ensure long-term integrity. 

A key feature of this model is its specified probe penetration depth of 8.5 inches, which determines how far the protected probe extends into the machinery for measurement.The 21000-28-05-00-085-03-02 is designed for versatile and secure field installation. It includes a threaded dome cover that screws onto the body to complete the explosion-proof seal, along with threaded ports for standard conduit connections. 

A particularly useful component is the integrated cable seal grip, supplied with a set of grommets to accommodate a wide range of external cable diameters from 1/8 inch to 3/8 inches.

As a complete system, the 21000-28-05-00-085-03-02 assembly contains all necessary parts for installation, including O-rings for sealing, a thread seal, and the reverse-mounted proximity probe itself. 

It is available with Canadian Standards Association (CSA) explosion-proof approvals, certifying its suitability for designated hazardous areas.
