330106-05-30-10-02-05 電渦流探頭

330106-05-30-10-02-05是一款電渦流探頭是電渦流傳感器，它基于電渦流效應(yīng)進(jìn)行工作。當(dāng)接通電源時(shí)，前置器內(nèi)部會(huì)產(chǎn)生一個(gè)高頻電流信號(hào)，該信號(hào)通過(guò)電纜送到探頭頭部，在頭部周圍產(chǎn)生交變磁場(chǎng)。當(dāng)被測(cè)導(dǎo)體（如金屬）接近這個(gè)交變磁場(chǎng)時(shí)，會(huì)在導(dǎo)體表面產(chǎn)生電渦流場(chǎng)，這個(gè)電渦流場(chǎng)會(huì)產(chǎn)生一個(gè)與原始磁場(chǎng)方向相反的交變磁場(chǎng)。這個(gè)反向磁場(chǎng)會(huì)改變探頭頭部線圈高頻電流的幅度和相位，即改變線圈的有效阻抗，從而改變傳感器的信號(hào)輸出。

電渦流探頭要求被測(cè)體必須是導(dǎo)體，330106-05-30-10-02-05其工作原理及特性與被測(cè)金屬間的距離、電導(dǎo)率、磁導(dǎo)率、線圈的幾何形狀、幾何尺寸以及電流頻率等參數(shù)有關(guān)。這種變化與金屬導(dǎo)體的電導(dǎo)率、磁導(dǎo)率、尺寸、金屬導(dǎo)體與探頭間距離、線圈激勵(lì)電流強(qiáng)度和頻率有關(guān)。在設(shè)計(jì)上，通過(guò)使上述除距離外的其他參數(shù)保持不變，可以使傳感器輸出信號(hào)與距離在一定范圍內(nèi)呈線性關(guān)系。

電渦流探頭在安裝時(shí)，330106-05-30-10-02-05需要確保探頭間隙與輸出電壓落在線性范圍內(nèi)，以避免出現(xiàn)測(cè)量誤差。初始間隙電壓的設(shè)置也是關(guān)鍵，一般根據(jù)靈敏度要求進(jìn)行設(shè)定。

總的來(lái)說(shuō)，電渦流探頭作為電渦流傳感器的重要組成部分，在位移、振動(dòng)等參數(shù)的測(cè)量中發(fā)揮著關(guān)鍵作用。它以其高精度、高靈敏度和非接觸式測(cè)量等優(yōu)點(diǎn)，廣泛應(yīng)用于電力、機(jī)械、冶金、化工等各個(gè)領(lǐng)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.
