330106-05-30-10-02-05 电涡流探头

330106-05-30-10-02-05是一款电涡流探头是电涡流传感器，它基于电涡流效应进行工作。当接通电源时，前置器内部会产生一个高频电流信号，该信号通过电缆送到探头头部，在头部周围产生交变磁场。当被测导体（如金属）接近这个交变磁场时，会在导体表面产生电涡流场，这个电涡流场会产生一个与原始磁场方向相反的交变磁场。这个反向磁场会改变探头头部线圈高频电流的幅度和相位，即改变线圈的有效阻抗，从而改变传感器的信号输出。

电涡流探头要求被测体必须是导体，330106-05-30-10-02-05其工作原理及特性与被测金属间的距离、电导率、磁导率、线圈的几何形状、几何尺寸以及电流频率等参数有关。这种变化与金属导体的电导率、磁导率、尺寸、金属导体与探头间距离、线圈激励电流强度和频率有关。在设计上，通过使上述除距离外的其他参数保持不变，可以使传感器输出信号与距离在一定范围内呈线性关系。

电涡流探头在安装时，330106-05-30-10-02-05需要确保探头间隙与输出电压落在线性范围内，以避免出现测量误差。初始间隙电压的设置也是关键，一般根据灵敏度要求进行设定。

总的来说，电涡流探头作为电涡流传感器的重要组成部分，在位移、振动等参数的测量中发挥着关键作用。它以其高精度、高灵敏度和非接触式测量等优点，广泛应用于电力、机械、冶金、化工等各个领域。

330106-05-30-10-02-05 is an eddy current probe is an eddy current sensor, it works based on the eddy current effect. When the power is turned on, a high-frequency current signal is generated inside the preprocessor, which is sent through the cable to the probe head, creating an alternating magnetic field around the head. When the measured conductor (such as a metal) approaches this alternating magnetic field, an eddy current field is generated on the conductor surface, which creates an alternating magnetic field in the opposite direction to the original magnetic field. This reverse magnetic field changes the amplitude and phase of the high-frequency current in the coil at the head of the probe, that is, changes the effective impedance of the coil, and thus changes the signal output of the sensor.

Eddy current probe requires that the measured body must be a conductor, 330106-05-30-10-02-05 Its working principle and characteristics are related to the distance between the measured metals, electrical conductivity, permeability, coil geometry, geometric size and current frequency and other parameters. This change is related to the conductivity, permeability, size of the metal conductor, the distance between the metal conductor and the probe, the coil excitation current intensity and frequency. In the design, by keeping the above parameters unchanged except the distance, the sensor output signal can be linear with the distance in a certain range.

When the eddy current probe is installed, 330106-05-30-10-02-05 it is necessary to ensure that the probe gap and the output voltage fall in a linear range to avoid measurement errors. The setting of the initial gap voltage is also key and is generally set according to the sensitivity requirements.

In general, the eddy current probe, as an important part of the eddy current sensor, plays a key role in the measurement of displacement, vibration and other parameters. Because of its high precision, high sensitivity and non-contact measurement, it is widely used in electric power, machinery, metallurgy, chemical industry and other fields.
