SENSOR FOR DETERMINING THE ELECTRICAL CONDUCTIVITY OF LIQUID MEDIA, AND METHOD FOR THE PRODUCTION THEREOF
First Claim
1. Sensor for determining the electric conductivity of liquid media comprising a multilayer layered structure, which comprises at least one carrier substrate, on which at least two magnetizable cores with metallic windings at least partially enclosing over the length of the cores are arranged, electrically conductive feed lines and drain lines to the windings of the at least two cores are available, and the multilayer layered structure is enclosed at least by a dielectric layer, wherein in order to exploit the inductive measuring principle the arrangement of the sensor realizes an at least partial enclosure of the two wrapped and encased cores or core parts by the liquid at the same time.

Abstract
Sensor for determining the electrical conductivity of liquid media comprising a multilayer layered structure (1), with a carrier substrate with two wound (3b, 4b) magnetizable cores (3a, 4a) and a dielectric coating. The invention also comprises a method in which a greenbody for a magnetizable core with metallic windings is applied onto a dielectric ceramic base green film, and a second magnetizable core with metallic windings is applied and subsequently a coating is applied before or after the sintering. The invention further comprises a method in which magnetizable cores with metallic windings are applied onto a dielectric organic base plate or base film.
