Sensor based on constructive elements of surface waves with capacitive coupling of high frequency connections.

摘要

Sensor based on constructive elements of surface waves, consisting of a housing with at least one component of surface waves, feed lines and discharge for high frequency signals, coupling capacitors whose surfaces capacitive coupling (3a, 3b) are applied on the one hand, the construction element surface wave and, on the other hand, opposite thereto on the housing, by means of which side the feeds and discharges the high-frequency signals for the element occur constructive wave surface (5), wherein the housing comprises a base plate (4) and a cover, wherein the base plate (4) is a plate modified circuit that supports a housing a frame attached to it sealingly to accommodate the components of surface waves, containing a fluid channel (6) and supporting one half of the coupling capacitors .
