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.

Features

  • Aluminum body construction with 304 stainless steel sleeve for corrosion resistance and mechanical protection
  • Configured with 4.2 inch (106.7 mm) probe penetration depth
  • Includes one cable seal grip with grommets to provide secure, weather-tight cable entry
  • CSA approved for hazardous area applications (Option 02)
  • Designed to meet API 670 standards for externally mounted proximity probe housings
  • Provides a stable mounting interface to reduce probe resonance and vibration

Applications

  • Oil and Gas: External probe mounting for turbomachinery monitoring
  • Power Generation: Vibration and axial position measurement on steam and gas turbines
  • Petrochemical: Hazardous area machinery protection and asset management
  • Rotating Machinery: Securing proximity probes in environments requiring explosion-proof protection
