      Technical notes

      Technical notes

      This model is an explosion-proof aluminum proximity probe housing assembly with a 13.3-inch sleeve. Its core configurations include: compatibility with a 3/8-24 threaded, 0.5-meter long probe, no rear conduit fitting, and a 5.0-inch housing height, certified with multiple global hazardous area approvals such as ATEX/IECEx. It is primarily used for the external probe installation and safety protection of large rotating machinery, including turbines and compressors.

      FAQS

      • What type of product is 21000-28-05-00-133-04-02?
        This is an externally mounted proximity probe housing assembly (aluminum body with a stainless steel sleeve structure) manufactured by Bently Nevada, which comes pre-installed with an internal eddy current sensor probe.
      • What is the primary purpose of 21000-28-05-00-133-04-02 in industrial sites?
        It is used on large rotating machinery like turbines and compressors to provide explosion-proof, waterproof, and oil-proof protection for the delicate probe inside, while enabling technicians to adjust the sensor gap, calibrate, or replace it from the outside without disassembling or stopping the machine.
      • Does the 21000-28-05-00-133-04-02 include a standoff adapter?
        The option "-00" means it is configured without an external standoff adapter (0 inches standoff), meaning the housing body will be mounted directly against the machine casing.
      • What are the physical materials and structural composition of 21000-28-05-00-133-04-02?
        Its dome cover and main junction box body are made of lightweight, high-strength die-cast aluminum (with a corrosion-resistant coating), while the 13.3-inch long penetration sleeve is constructed from highly rigid 304 stainless steel.
      • How to correctly install, adjust, and use 21000-28-05-00-133-04-02 on site?
        Insert the sleeve into the casing hole and tighten the 3/4-14 NPT process thread. Unscrew the upper aluminum dome cover to directly adjust the insertion depth of the internal probe from the outside to calibrate the installation gap (typically until ~-10V DC is monitored at the Proximitor), then route the 0.5m integral cable through the conduit to connect with the extension cable.
