Description

The 21000-00-00-00-250-03-02 is a robust proximity probe housing assembly designed for industrial machinery vibration monitoring applications. This specific configuration features a 25.0 inch probe penetration depth (Option 250) and is equipped with a cable seal grip fitting (Option 03) and 3/4-14 NPT mounting threads (Option 02). As a standard 21000 series housing, it utilizes an aluminum body with a stainless steel sleeve to protect internally mounted proximity probes from harsh environmental conditions.

This assembly configuration does not include a pre-installed probe or cable (Options 00 for A and B) and is provided without a standoff adapter (Option 00 for C). It is compatible with 3300 XL and 3300 NSv proximity transducer systems, providing the necessary mechanical protection for probes in demanding process environments such as power generation, oil and gas, and petrochemical facilities. The 21000 series ensures compliance with industry standards for externally mounted proximity probe housings.

Features

  • Aluminum body construction with 304 stainless steel sleeve
  • Probe penetration: 25.0 inches (Option 250)
  • Mounting thread: 3/4-14 NPT (Option 02)
  • Fittings: Includes one cable seal grip with grommets (Option 03)
  • Designed for 3300 XL 8mm, 11mm, and NSv proximity probes
  • Meets API 670 standards for externally mounted proximity probe housings

Installation Guidelines

For hazardous area applications, ensure all fittings are installed correctly to maintain the integrity of the explosion-proof enclosure.
