SENSOR BASED ON SURFACE WAVE COMPONENTS WITH CAPACITIVE COUPLING OF THE HIGH FREQUENCY CONNECTIONS

摘要

Sensor on the basis of surface waves - components, consisting of a housing having at least one surface waves - component (5), a base plate (4) with too - and outlet lines for high-frequency signals and capacitive coupling surfaces, which at the at least one surface waves - component (5) and, opposite, on the base plate (4) are mounted, characterized in that the capacitive coupling surfaces (3a) which, at the surface waves - component (5) are mounted, by a distance or a dielectric separately, by the capacitive coupling surfaces (3b), on the base plate (4) are mounted, and a fluid channel (6) in such a way in the base plate (4) is introduced, so that the fluid between the capacitive coupling surfaces (3a, 3b) is guided, with the resonator structure (1) of the surface waves - component (5) comes into contact.
