All prices are shown in USD.
      Eddy current proximity sensor or system component, commonly used in the monitoring of industrial rotating machinery. Its working principle is based on high-frequency electromagnetic field coupling and the eddy current effect, and it is mainly used for non-contact measurement of shaft vibration, displacement, or axial motion.
      Material: The main body of the housing is made of aluminum alloy, and the probe sleeve is made of 304 stainless steel.
      Compliance: Fully compliant with American Petroleum Institute (API) 670 standards, suitable for external proximity probe housings.
      Protection Rating: CSA Type 4 housing certified, explosion-proof rating meets hazardous area standards.

      FAQ

      View All Faqs
      • In which specific industrial environments is the 21000-16-10-00-046-04-02 sensor designed for non-contact displacement sensor measurements?
        The 21000-16-10-00-046-04-02 is primarily used in heavy-duty rotating machinery where the linear measurement range requirements far exceed the capabilities of a standard 8mm probe. As a 16mm diameter sensor, the 21000-16-10-00-046-04-02 excels at monitoring the axial thrust position and differential pressure expansion of large steam turbines and centrifugal compressors, providing critical data for the protection of these "machine units."
      • What mechanism does 21000-16-10-00-046-04-02 employ to maintain signal fidelity over a 4.6-meter transmission path?
        The 21000-16-10-00-046-04-02 uses impedance-matched coaxial cable and special dielectric insulation to reduce signal attenuation. As part of a tuned resonant circuit, its specific length is calculated to maintain a stable average scaling factor (ASF) of 100 mV/mil (approximately 3.94 V/mm), ensuring Proximitor® can interpret eddy current losses with sub-micron accuracy.
      • Why is the “04-02” termination on the 21000-16-10-00-046-04-02 critical for long-term operational reliability in high-vibration environments?
        The “04-02” designation in the 21000-16-10-00-046-04-02 model number indicates that it includes a dedicated connector protector and a standard miniature coaxial connector. This configuration prevents the 21000-16-10-00-046-04-02 from experiencing connector fretting wear or moisture damage, which are major causes of signal "failures" and false triggers in industrial vibration monitoring systems.
      • How does the 21000-16-10-00-046-04-02 perform in terms of resistance to galvanic corrosion and strong chemical reagents?
        The 21000-16-10-00-046-04-02's housing is made of 300 series stainless steel, while the probe tip is constructed from high-performance polyphenylene sulfide (PPS). This synergistic material combination allows the 21000-16-10-00-046-04-02 to be immersed in acidic or alkaline lubricants without compromising the structural integrity of its internal eddy current coil.
      • Which specific API 670 standards does integrating the 21000-16-10-00-046-04-02 into a mechanical protection system meet?
        The 21000-16-10-00-046-04-02 meets the stringent linearity and temperature stability requirements specified by the American Petroleum Institute (API) 670 standard. By providing a wide linear range (typically up to 4.0 mm (160 mils)), the 21000-16-10-00-046-04-02 ensures that catastrophic axial displacement can be detected before the rotor comes into contact with stationary components.
