07CR41 涡流传感器通常由一个激励线圈和一个检测线圈组成

涡流传感器是一种非接触的线性化计量工具，07CR41 能静态和动态地非接触、高线性度、高分辨力地测量被测金属导体距探头表面的距离。它利用电涡流原理来测量位移、距离和可以转化为位移量的其他物理量。其优点包括长期工作可靠性好、灵敏度高、抗干扰能力强、非接触测量、响应速度快、不受油水等介质的影响等。涡流传感器常被用于对大型旋转机械的轴位移、轴振动、轴转速等参数进行长期实时监测，可以分析出设备的工作状况和故障原因，有效地对设备进行保护及预维修。

涡流传感器的原理基于法拉第电磁感应定律和涡旋电流的相互作用。07CR41 当导体相对于磁场运动或磁场发生变化时，会在导体中产生感应电流。而涡旋电流则是指在导体中形成旋转的环形电流分布。涡旋电流的产生是由于导体中的自感和电阻的相互作用，当导体中存在变化的磁场时，涡旋电流会抵消磁场的变化，从而形成一个反向的感应电磁场。

涡流传感器通常由一个激励线圈和一个检测线圈组成。07CR41激励线圈通过通电产生一个交变磁场，而检测线圈则用来感应涡旋电流产生的感应电磁场。当涡旋电流在金属导体表面产生时，感应电磁场会改变检测线圈中的电压输出，从而实现对金属导体的测量。

涡流传感器具有非接触性、不损伤性、快速、准确等优点，被广泛应用于各种领域，如电力、钢铁、石化、陶瓷和机械制造等行业的设备检测和维护。

Eddy current sensor is a non-contact linearization measuring tool, 07CR41 can statically and dynamically non-contact, high linearity, high resolution measurement of the measured metal conductor distance from the probe surface. It uses the principle of eddy currents to measure displacement, distance and other physical quantities that can be converted into displacement quantities. Its advantages include good long-term reliability, high sensitivity, strong anti-interference ability, non-contact measurement, fast response speed, not affected by oil and water and other media. Eddy current sensor is often used for long-term real-time monitoring of the axis displacement, shaft vibration, shaft speed and other parameters of large rotating machinery, which can analyze the working condition and fault causes of the equipment, and effectively protect and pre-repair the equipment.

The principle of eddy current sensor is based on Faraday’s law of electromagnetic induction and the interaction of vortex current. 07CR41 When a conductor moves with respect to a magnetic field or when the magnetic field changes, an induced current is generated in the conductor. The vortex current is a circular current distribution that forms a rotation in the conductor. The generation of vortex current is due to the interaction of self-inductance and resistance in the conductor. When there is a changing magnetic field in the conductor, the vortex current will offset the change in the magnetic field, thus forming a reverse induced electromagnetic field.

Eddy current sensors usually consist of an exciting coil and a detecting coil. The 07CR41 excitation coil is energized to generate an alternating magnetic field, while the detection coil is used to sense the induced electromagnetic field generated by the vortex current. When the eddy current is generated on the surface of the metal conductor, the induced electromagnetic field will change the voltage output in the detection coil, thus realizing the measurement of the metal conductor.

Eddy current sensors have the advantages of non-contact, non-damage, fast, accurate, etc., and are widely used in various fields, such as power, steel, petrochemical, ceramics and machinery manufacturing industry equipment detection and maintenance.
