      Product Information:

      The 21000-00-00-55-060-03-02 is an industrial-grade external eddy current probe housing assembly from the Bently Nevada 21000 series. As standard mechanical protection hardware in the field of rotating machinery condition monitoring, it is designed to provide high-strength physical sealing and protection for external eddy current displacement probes on high-value rotating equipment such as steam turbines, compressors, and large pumps.

      The biggest advantage of the 21000-00-00-55-060-03-02 is that technicians can precisely adjust the internal probe's measurement gap directly from the outside of the machine without disassembling the housing or shutting down the equipment, making it an indispensable auxiliary component for industrial predictive maintenance. Core hardware and customized parameter analysis: The main body of the assembly is made of A356.0 cast aluminum, and the internal probe sleeve is made of 304 stainless steel, offering excellent impact resistance and resistance to industrial chemical corrosion.

      Based on its highly customized long suffix parameter code, 21000-00-00-55-060-03-02 has a very unique configuration: the first two options, 00-00, indicate that the component is shipped without an internal probe and coaxial cable, making it an empty shell component that allows users to add existing 3300 XL 8mm or 5mm probes in the field; option 55 indicates that it is equipped with a highly flexible stainless steel armored conduit to enhance the mechanical damage resistance of the external cable; the machine penetration depth of the conduit is 6.0 inches, approximately 152 mm (option 060); the conduit fitting includes a 3/4-14 NPT armored fitting (option 03); the entire component is screwed into the measuring hole on the machine bearing housing via a 3/4-14 NPT industry standard thread (option 02).

      In security monitoring and industrial network integration, the protective housing assembly, after being correctly assembled on site, can provide all-weather environmental protection for the internal sensitive sensing elements. Its housing meets the high-level splash-proof, dust-proof, and explosion-proof standards of CSA Type 4 (weatherproof housing), and the mechanical structure design fully complies with the strict technical specifications of the American Petroleum Institute API 670 mechanical monitoring hardware standard.
      The coaxial cable is safely led out from the armored flexible tube of the protective housing and connected to the field preamplifier, and finally the linear voltage signal is connected to the Bently Nevada 3500 mechanical protection system. This system is widely used in harsh heavy industrial places such as petrochemical, large power, and heavy metallurgy, which are characterized by high temperature, high oil content, and flammability and explosiveness, to ensure the absolute stability and security of the underlying physical monitoring signal.

      Technical notes

      The 21000-00-00-55-060-03-02 is a Bently Nevada 21000 series external all-metal probe housing assembly. Its housing is made of aluminum alloy (covered with a 304 stainless steel sheath), and the overall design fully complies with API 670 standards and has a CSA Type 4 industrial protection rating. Unlike common built-in probe assemblies, the core technical feature of this model is its flexible and customizable "empty shell" configuration: the probe can be equipped with an eddy current probe (-00) or without a probe cable (-00), but a 5.5-inch high bracket adapter (-55) is included as standard to avoid external obstructions. The stainless steel sheath provides a 6.0-inch probe penetration depth (-060), and electrical interface accessories include a 3/4-14 NPT threaded connector. The plug, 1/2-14 NPT reducer and three sizes of cable seal connectors (-03) are secured by a 3/4-14 NPT thread (-02) on the bottom, allowing field engineers the flexibility to select or replace the internal reverse-mount probe while retaining the original housing.
