Bently Nevada 21000-00-00-00-042-03-02 Proximity Probe Housing Assembly

Description

The 21000-00-00-00-042-03-02 is an aluminum proximity probe housing assembly designed for the external mounting of industrial proximity probes. This specific configuration features a 4.2 inch probe penetration depth (Option 042), includes one cable seal grip with grommets (Option 03), and meets requirements for Canadian Standards Association (CSA) approval (Option 02). Engineered for durability, the 21000 series provides a protective, weather-resistant environment for the probe and its connector, ensuring reliable performance in harsh industrial surroundings.

This housing assembly is fully compliant with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings. The aluminum body is equipped with a 304 stainless steel sleeve to enhance mechanical integrity. This unit is intended for applications where probe accessibility and environmental protection are critical, offering a robust method to secure sensors on rotating machinery such as turbines, compressors, and pumps.
