    • A doctor for a paper machine that according to some implementations includes a blade, a wearing element located in or on the blade so that at least a portion of the wearing element is exposed to wear as the blade is worn, and a reading element positioned in proximity to the wearing element. The reading element is configured to emit a magnetic signal to excite the wearing element and the wearing element is configured to respond to the magnetic signal with a magnetic response signal. The reading element is in turn configured to receive the magnetic response signal, the magnetic response signal comprising a frequency that varies with the wear of the wearing element such that the frequency of the magnetic response signal is representative of the wear of the wearing element.
    • 用于造纸机的医生根据一些实施方式包括刀片,位于刀片中或刀片上的磨损元件,使得磨损元件的至少一部分在刀片磨损时暴露于磨损,并且读取元件位于 靠近磨损元件。 读取元件被配置为发射磁信号以激励磨损元件,并且磨损元件被配置为响应于具有磁响应信号的磁信号。 读取元件又被配置成接收磁响应信号,磁响应信号包括随着磨损元件的磨损而变化的频率,使得磁响应信号的频率代表磨损元件的磨损。
