Description

Отличительна  особенность онисываемого конденсатора к прибору дл  измерени  влажности твердых тел по их диэлектрической посто ниой состоит в конструктивном выполнении его электродов в виде концентрически расположенных в одной плоскости кольцевых металлических пластин, укрепленных на общем держателе.A distinctive feature of an onsisable capacitor to a device for measuring the moisture content of solids by their dielectric constants is the structural design of its electrodes in the form of annular metal plates mounted concentrically in one plane, mounted on a common holder.

На фиг. 1 и 2 приведе 1ы две проекции предлагаемого конденсатора .FIG. 1 and 2 give 1y two projections of the proposed capacitor.

Два (или больгие) нлоских концентрических электрода 1 и 2, выполненных в виде кольцевых металлических пластин, укреплены на общем держателе 3 из твердого диэлектрика. При измерении влажности конденсатор своими электродами прижимаетс  к поверхности исследуемого материала 4. Путем подбора толщины электродов 1 и 2 и рассто ни  между ними Ь, можно обеспечить проникновение силовых линий в исследуемый материал на минимальную глубину и, следовательно, устранить вли ние размеров образца на измерени . Линии пол  будут частично замыкатьс  и по поверхности образца, что не преп тствует измерению влажности, производимому по шкале с эмпирической градуировкой , учитывающей суммарный эффект емкости и поверхностной проводимости.Two (or large) flat concentric electrodes 1 and 2, made in the form of annular metal plates, are mounted on a common holder 3 made of a solid dielectric. When measuring the moisture, the capacitor with its electrodes is pressed against the surface of the material under study 4. By selecting the thickness of electrodes 1 and 2 and the distance between them b, it is possible to ensure the penetration of lines of force into the material under study to the minimum depth and, therefore, eliminate the influence of the sample size on the measurements. The field lines will be partially closed along the surface of the sample, which does not interfere with the measurement of moisture produced on a scale with an empirical graduation, taking into account the total effect of capacitance and surface conductivity.

Конденсатор позвол ет измер ть влажиость и в тех случа х, когда достуипа лишь одна поверхность исследуемого тела или когда это тело не имеет правильной геометрической формр г. В последнем случае достаточно создать плоскую поверхность с площадью, равной площади конденсатора.The capacitor allows you to measure moisture in those cases where access is only one surface of the body under study or when this body does not have the correct geometric shape. In the latter case, it is sufficient to create a flat surface with an area equal to the area of the capacitor.

Если необходимо в течение длительного времени контролировать влажность в определенной зоие образца, электроды 1 и 2 в виде тонких слоев металла иаиос т непосредственно на исследуемый материал путем расиылени . Это позвол ет быстро и дешево изготовить большое количество конденсаторов и устран ет погрешность, обусловливаемую наличием дополнительной емкости, создаваемой между смежными кра ми электродов.If it is necessary to control the humidity in a certain area of the sample for a long time, electrodes 1 and 2 in the form of thin layers of metal are directly applied to the material under investigation by scattering. This allows a large number of capacitors to be fabricated quickly and cheaply, and eliminates the uncertainty caused by the presence of additional capacitance created between the adjacent edges of the electrodes.
