            The sensor (hereinafter referred to as a sensor) can measure the relative position of the measured body (which must be a metal conductor) and the end of the probe. Because of its non-contact measurement, long-term high reliability, high sensitivity and strong anti-interference ability, fast response, no influence of oil and water, is often used for long-term real-time monitoring of the parameters of the axial displacement, large rotating machinery shaft vibration, shaft speed, working condition and fault reasons can be divided into precipitation equipment, protection and predictive maintenance of equipment effectively. The displacement, amplitude, speed, size, thickness, surface unevenness and so on can be measured. From the theoretical analysis of rotor dynamics and bearing science, the running state of large rotating machinery is mainly determined by its core rotating shaft. The eddy current displacement sensor can directly measure the state of the rotating shaft, and the measurement results are reliable and credible.

            A brief introduction to Section 1
            The leading technology of the JX20 series of eddy current displacement sensors:
            1, "the matching of the optimum temperature stability parameters of the coil" ensures a good temperature stability of the probe.
            2, adopt the new PPS engineering plastics through the "two times injection molding" process, ensure good sealing, dimensional stability and interchangeability of the probe, and extend the working temperature range to -50 C to +175 C.
            3, "deformation joint" process combination, higher intensity and reliability of the probe.
            4, the technology of "deep negative feedback stable resonant circuit" makes the stability of the preposition (0.05%/, 0.02%/).
            5. Design and production according to the standard of the United States, the prefix can work for a long time in the environment of -50 ~ +105.
            6. Fault tolerance design is adopted in the predevice circuit to ensure that any connection error will not be damaged.
            7. The preposition device uses the latest electronic technology, and the power consumption is less than 12mA.
            8, the front part housing is made of die casting technology, high frequency socket concave and wiring terminal mosaic protection, engineering plastics isolation insulation and other structures, so that the front end device is more sturdy, and the installation and use are more convenient.
