      Product Information:

      The 21000-32-05-00-038-03-02 is an external mounting and protective housing assembly for the 21000 series metal eddy current probe, manufactured by Bently Nevada. This assembly is a fully compliant, API 670-compliant, mechanically integrated hardware system specifically designed for mounting on the bearing housing surfaces of large steam turbines, centrifugal compressors, and various high-pressure industrial pumps.

      The core advantage of the 21000-32-05-00-038-03-02 is that it allows field maintenance personnel to safely calibrate, disassemble, or replace the internal probe directly from the outside of the machine without stopping the machine or disassembling the machine casing, greatly simplifying the daily dynamic monitoring and maintenance process for rotating machinery.

      Because the assembly has passed the certifications of mainstream international explosion-proof systems such as ATEX, IECEx and CSA, it is widely deployed in high-risk, flammable and explosive gas control areas such as petrochemical plants and large modern power plants, providing the most robust safety barrier for millisecond-level interlocking trip protection of core rotating assets.

      View All Faqs
      • What are the main engineering applications of the 21000-32-05-00-038-03-02 probe in precision rotating machinery protection systems?
        The 21000-32-05-00-038-03-02 is an eddy current proximity probe assembly designed for advanced non-contact measurement of shaft vibration, radial displacement, axial position, and rotor dynamic characteristics. As a high-reliability sensing component in calibrated proximity sensor systems, it is used for continuous mechanical condition monitoring and asset protection.
      • How does the 21000-32-05-00-038-03-02 utilize the eddy current electromagnetic principle to achieve high-resolution displacement detection?
        The 21000-32-05-00-038-03-02 employs an electromagnetic eddy current sensing mechanism, where a high-frequency electromagnetic field is generated at the probe tip. Changes in the gap between the probe and the target alter the induced eddy currents in the conductive shaft material, thereby producing a proportional output signal with excellent linearity, repeatability, sensitivity, and dynamic measurement response.
      • What are the probe body structure and mechanical characteristics of 21000-32-05-00-038-03-02?
        21000-32-05-00-038-03-02 uses a 32 mm probe body structure, with order code 32. This precision-designed probe structure provides reliable mechanical integration, higher rigidity, and stable sensing performance for demanding rotating equipment applications.
      • What are the integrated cable length specifications for 21000-32-05-00-038-03-02?
        21000-32-05-00-038-03-02 includes a 5-meter (16.4-foot) integrated precision coaxial cable, configuration code 05. This cable assembly is designed to maintain controlled electrical characteristics and is compatible with matching extension cables and signal conditioning electronics.
      • How to maintain the integrity of measurement signals in industrial environments with high electrical noise?
        21000-32-05-00-038-03-02 A shielded impedance-controlled coaxial cable design is used to reduce signal attenuation, electromagnetic interference (EMI), radio frequency interference (RFI), and unwanted electrical noise. This optimized transmission structure ensures accurate and stable displacement signal acquisition.
