Description
среза ДТ, состо щего из кварцевой пластины 1, на главные грани которой нанесены возбуждающие электроды 2 и 3. К электродам подводитс высокочастотное напр жение при помощи струн-токоотводов 4, расположенных в узловых точках пластины с одной ее стороны, причем средний токоотвод электрически св зан, например, нри помощи токопровод щей дорожки 5 с электродом 3. Наружна поверхность электрода 3 выполнена шероховатой , и на нее нанесен слой оксиметилироваппого сополнамида 6, причем после нанесени слой подвергают термообработке.cut DT, consisting of a quartz plate 1, the main face of which is applied to the exciting electrodes 2 and 3. The electrodes are supplied with high-frequency voltage by means of strings 4, located at the nodal points of the plate on one side, and the middle current lead is electrically connected For example, using a conductive path 5 with electrode 3. The outer surface of electrode 3 is roughened and a layer of oximethylium copolyamide 6 is applied to it, and after being applied, the layer is subjected to heat treatment.
Предмет изобретени Subject invention
Пьезокварцевый датчик влажности газов пограничного сло , содержащий кварцевуюA piezoelectric sensor for the humidity of gases in a boundary layer containing quartz
пластину, два электрода с влагочувствительным слоем и жесткие струны-токоотводы, расположенные в узловых точках граней кварцеЕой пластины, о т л и ч а ю щ и и с тем, что,a plate, two electrodes with a moisture-sensitive layer and rigid string-current leads located at the nodal points of the faces of the quartz plate of the E plate, so that
с целью обеспечени возможности измерени влажности газов в плоскости, параллельной поверхности исследуемого объекта, и повыплени точности измерени , струны-токоотводы расположены только на одной грани пластипы , а свободна от струн-токоотводов поверхность второго электрода выполнена щероховатой , покрыта слоем оксиметилированного сополиамида и соединена электрически с одной из изолированных от остальных струн-токоотводов посредством проход щей через ребро кварцевой пластипы полосы металла.in order to ensure the measurement of the moisture content of gases in a plane parallel to the surface of the object under study, and to increase the measurement accuracy, the lead strings are located only on one side of the plastip, and the surface of the second electrode is made rough, covered with a layer of hydroxymethylated copolyamide and electrically connected one of the strings, isolated from the other strings, by means of a strip of metal passing through an edge of quartz plastips.
