Description

The 21000-16-05-00-066-04-02 is an aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This unit protects the probe and its connector in industrial environments, ensuring secure installation for machinery shaft vibration and axial position monitoring. This configuration includes a 3300 XL 8 mm proximity probe (Option 16), a 0.5 m cable length (Option 05), no standoff adapter (Option 00), a 6.6 in probe penetration (Option 066), one 3/4-14 NPT plug fitting (Option 04), and 3/4-14 NPT mounting thread (Option 02). The 21000 housing series is built for durability with an aluminum body and 304 stainless steel sleeve, providing a robust, all-metal enclosure that complies with the American Petroleum Institute (API) 670 Standard for externally mounted housings. This assembly is designed to be used in conjunction with 3300 XL proximity transducer systems, providing the necessary mechanical protection for cable terminations and probe mounting in critical rotating machinery applications.

Features

  • Option 16: Includes factory-installed 3300 XL 8 mm proximity probe.
  • Option 05: 0.5 m (20 in) probe cable length.
  • Option 00: No standoff adapter included.
  • Option 066: Probe penetration depth set to 6.6 in.
  • Option 04: Fittings configuration featuring one 3/4-14 NPT plug.
  • Option 02: Mounting thread 3/4-14 NPT.
  • Construction: Aluminum body with 304 stainless steel sleeve for corrosion resistance and structural integrity.
  • Compliance: Fully compliant with API 670 standards for externally mounted housings.

Applications

  • Oil and Gas: External probe mounting on compressors, turbines, and pumps.
  • Power Generation: Shaft vibration monitoring on balance-of-plant machinery.
  • Petrochemical: Hazardous area machinery protection (verify specific local certification requirements).
  • General Industrial: Any rotating equipment requiring external probe access where standard NPT threading is utilized.
