    • The contactless magnetic sensor consists of at least one excitation coil (10) connected to the source (20) of alternating signal. In thejcavity of the excitation coil (10) is located a magnetic field sensor (40) and its output is connected to the input of the amplifier (60). The sensor includes an excitation modulator (21), which is connected to the source (20). Output of the amplifier (60) is connected to the input of a low-pass filter (80), to the input of a band-pass filter (81), and to the input of a high-pass filter (82). The source (20) generates alternating, advantageously rectangular-shaped current, which generates an alternating current magnetic field around the excitation coil (10) that interacts with materials in the excitation coil (10) vicinity. The magnetic field sensor (40) may be an anisotropic magnetoresistor AMR or a Hall probe. In case of an AMR sensor the excitation signal of the excitation coil (10) is connected via the separating capacitor (30) directly to the flipping input of the AMR sensor coil. Since the excitation signal of the excitation coil (10), and therefore the generated magnetic field are in-phase, and the magnetic field sensor's output is modulated by the flipping circuit, the result is a controlled rectification of the sensor's output signal and self-demodulation of the output signal. The output of the sensor may therefore be used for position detection, proximity detection or discrimination of materials in the coil vicinity.
    • 非接触磁传感器由连接到交流信号源(20)的至少一个励磁线圈(10)组成。 在励磁线圈(10)的腔中设置有磁场传感器(40),其输出端连接到放大器(60)的输入端。 传感器包括与源极(20)连接的激励调制器(21)。 放大器(60)的输出端与低通滤波器(80)的输入端连接到带通滤波器(81)的输入端,连接到高通滤波器(82)的输入端。 源极(20)产生交替的,有利矩形的电流,其产生与激励线圈(10)附近的材料相互作用的激励线圈(10)周围的交流磁场。 磁场传感器(40)可以是各向异性磁阻电阻器AMR或霍尔探头。 在AMR传感器的情况下,励磁线圈(10)的激励信号经由分离电容器(30)直接连接到AMR传感器线圈的翻转输入。 由于励磁线圈(10)的激励信号,因此产生的磁场是同相的,并且磁场传感器的输出由翻转电路调制,结果是对传感器的输出信号进行可控整流, 解调输出信号。 因此,传感器的输出可以用于线圈附近的位置检测,接近检测或材料的辨别。

    • The systems and methods of the invention pertain to analyzing steam generator tube data for the detection of wear. Further, the invention is capable of performing a comparison of current tube signal data to baseline or historic tube signal data, e.g., from previous and/or the first, in-service inspection of the steam generator. The systems and methods are automated and can generate results to show potential tube-to-tube contact wear areas as well as the progression of tube-to-tube gap reduction within a steam generator tube bundle. In certain embodiments, the invention is capable of comparing current and historical eddy current data to determine the difference that may be related to degradation or other interested phenomena, and of processing and trending historical comparison results to establish normal variance and detect abnormal variances.
