Description

Обычно примен емые способы определени  глубины проникновени  электромагнитного пол  в металл с помощью датчика и экрана, вводимого в исследуемое поле, пригодны лишь дл  однородного пол  плоских электромагнитных волн.The commonly used methods for determining the depth of penetration of an electromagnetic field into a metal by means of a sensor and a screen introduced into the field under study are suitable only for a uniform field of plane electromagnetic waves.

Описываемый способ позвол ет производить измерение глубины проникновени  неравномерного электромагнитного пол . Это достигаетс  тем, что в качестве датчика ииспользуют излучатель, создающий исследуемое поле, дл  чего измер ют его электрические параметры (например , полное сопротивление), измен ющиес  при внесении в это поле экранов разной толщины.The described method allows the measurement of the penetration depth of an uneven electromagnetic field. This is achieved by using an emitter that creates the field under study as a sensor, for which its electrical parameters (for example, impedance), which vary with the introduction of screens of different thickness, are measured.

На чертеже изображены кривые зависимости свойств датчика от толщины фольг из различных материалов.The drawing shows the curves of the properties of the sensor from the thickness of the foil of various materials.

Определение глубины проникновени  неравномерного электромагнитного пол  (специальной формы) производитс  не по измерению величинь проникшего пол , а по прекращению изменени  электрических свойств излучател  при увеличении толщины изучаемого сло  или. фольги: толщина сло  мен етс  от толщин меньщих глубины проникновени  до толщин больших ее.The determination of the penetration depth of an uneven electromagnetic field (of a special form) is made not by measuring the size of the penetrated field, but by stopping the change in the electrical properties of the radiator with increasing thickness of the layer being studied or. foil: the thickness of the layer varies from the thickness of the smaller penetration depths to the thickness of its greater.

Дл  производства измерений глубины проникновени  пол  датчика создаетс  система (например, Т-образный мостик), определ юща  его свойства, и снимаютс  кривые зависимости комплексных свойств датчика от толщины фольг из различных материалов (например, Си, А), Zn, латуни и Sn). Из кривых (фиг. 1) видно, что при достижении некоторой толщины фольги, полное сопротивление Z датчика далее не мен етс .To make measurements of the penetration depth of the sensor floor, a system is created (for example, a T-shaped bridge), which determines its properties, and curves are plotted based on the complex properties of the sensor on foil thickness from various materials (for example, Cu, A), Zn, brass, and Sn) . From the curves (Fig. 1), it can be seen that when a certain foil thickness is reached, the impedance Z of the sensor does not change further.

Подобным образом можно также определ ть потери пол .Similarly, the loss of gender can also be determined.

Предмет изобретени Subject invention

Способ определени  глубины проникновени  электромагнитного пол  в металл с помощью датчика и экрана, вводимого в исследуемое поле, отличающийс  тем, что, с целью возможности производства измерений в неравномерных пол х, в качестве датчика используют излучатель , создающий исследуемое поле, дл  чего измер ют его электрические параметры (например, полное сопротивление), измен ющиес  при внесении в это поле экранов разной толщины, и глубину проникновени  определ ют по толщине того экрана, при котором прекращаетс  изменение параметров излучател .The method for determining the penetration depth of an electromagnetic field into a metal by means of a sensor and a screen introduced into a test field, characterized in that, in order to make measurements in non-uniform fields, an emitter creating the test field is used as a sensor, for which electric the parameters (for example, the impedance), which vary when screens of different thickness are introduced in this field, and the penetration depth is determined by the thickness of the screen at which the parameters from radiant
