Description
тушки 3 и 4, оси которых параллельны плоскости витков катушки 2.carcasses 3 and 4, the axes of which are parallel to the plane of the turns of coil 2.
Катушка возбуждеии 2 подключена к генератору переменного тока, выводы измерительных катушек 3 и 4 --к регистрирующей аппаратуре.Excitation coil 2 is connected to an alternator, the terminals of measuring coils 3 and 4 are connected to the recording equipment.
Датчик работает следующим образом.The sensor works as follows.
При наличии контролируемого издели первичное магнитное поле, создаваемое катушкой возбуждени 2, создает в металле вихревые токи, навод ш,ие в измерительной катушке 3 ЭДС, амплитуда которой пропорциональна как контролируемому перемеш,ению металлического издели , так и температуре окружающей среды. Выходной сигнал измерительной катушки 4 пропорционален только температуре окружающей среды, так как ось чувствительности данной катушки перпендикул рна к направлению магнитного потока вихревых токов.In the presence of a controlled product, the primary magnetic field created by the excitation coil 2 creates eddy currents in the metal, which induces an emf in the measuring coil 3, the amplitude of which is proportional to both the controlled stirring, the metallic product and the ambient temperature. The output signal of the measuring coil 4 is proportional only to the ambient temperature, since the sensitivity axis of this coil is perpendicular to the direction of the magnetic flux of eddy currents.
Таким образом, результирующий выходной сигнал датчика, вл сь разностным, зависит только от контролируемого перемещени и не зависит от температуры окружающей среды.Thus, the resulting sensor output, which is differential, depends only on the controlled movement and does not depend on the ambient temperature.
В отсутствии издели ЭДС в измерительной катушке 3 не наводитс , так как катушка возбуждени 2 и измерительна катушка 3 установлены во взаимно перпендикул рных плоскост х.In the absence of an article, the EMF in the measuring coil 3 is not induced, since the excitation coil 2 and the measuring coil 3 are installed in mutually perpendicular planes.
