      Product Information:

      The Proximity Probe Housing Assembly (PPHA), model number 21000-28-05-00-130-04-02, is compatible with the 21000 Series Eddy Current Sensor Probes manufactured by Bently Nevada (a subsidiary of Baker Hughes). This assembly is designed for monitoring bearing vibration and displacement in large rotating machinery, such as steam turbines, compressors, and fans, and conforms to the API 670 international standard.

      The 21000-28-05-00-130-04-02 housing features a 3/4-14 NPT threaded plug (code 04), and the entire assembly is securely screwed into the machine bearing housing via a standard 3/4-14 NPT thread (code 02). To meet the requirements of industrial field applications and environments, this protective housing typically utilizes a machined aluminum housing and a 304 stainless steel probe sleeve, combining lightweight construction with high mechanical strength.

      21000-28-05-00-130-04-02 has obtained international explosion-proof and intrinsically safe certifications such as CSA, making it suitable for hazardous areas containing flammable gases or vapors, and features a high level of waterproof and dustproof housing protection (CSA Type 4). This allows this high-precision measuring unit to continuously output reliable machine health data in extremely harsh industrial environments filled with high temperatures, high pressures, oil contamination, and severe vibrations.

      FAQ

      View All Faqs
      • What sensing technology does the 21000-28-05-00-130-04-02 probe use to achieve micron-level measurement accuracy?
        The 21000-28-05-00-130-04-02 probe uses high-frequency eddy current sensor technology to generate an electromagnetic field that responds to changes in the distance between the probe tip and a conductive target. This non-contact measurement principle offers excellent linearity, repeatability, and resistance to mechanical wear.
      • What are the probe configuration and dimensions of the 21000-28-05-00-130-04-02?
        The 21000-28-05-00-130-04-02 probe body uses an M10 × 1 thread, has a probe tip diameter of 5 mm, and a probe length of 130 mm. These dimensional characteristics facilitate installation in space-constrained machine tool housings while maintaining optimal sensing performance for rotating equipment.
      • What are the measurement range and sensitivity advantages of the 21000-28-05-00-130-04-02 in precision machinery diagnostics?
        The 21000-28-05-00-130-04-02 is designed for use with compatible proximity actuators and extension cables, providing a linear measurement range of approximately 2 mm (80 mils). This probe provides high-resolution displacement measurements and is suitable for monitoring shaft vibration, axial position, eccentricity, and rotor dynamics.
      • How to ensure high-frequency dynamic response in rotating equipment analysis?
        The 21000-28-05-00-130-04-02 has a wide frequency response range, enabling accurate detection of low-frequency shaft motion and high-frequency vibration phenomena. This dynamic performance allows engineers to diagnose imbalances, misalignments, mechanical loosening, oil swirl, and bearing-related instabilities.
      • Which cable configuration should be used for the 21000-28-05-00-130-04-02?
        The 21000-28-05-00-130-04-02 comes with a 5-meter integrated low-noise coaxial cable, carefully designed to maintain signal integrity and minimize electromagnetic interference (EMI). This cable is optimized for compatible extension cables and proximity sensor drivers to maintain calibrated system performance.
