Abstract

An inductive conductivity measurement cell of the invention includes: sending coil, a receiving coil, and a coil support body having an annular, sending coil chamber and an annular, receiving coil chamber, wherein there extends through the coil support body at least one section of a closed media path, which passes through the sending coil chamber and through the receiving coil chamber, characterized in that the coil support body has first connection bores, which extend from a surface of the coil support body to the sending coil chamber and through which the connection lines of the sending coil extend, and second connection bores, which extend from a surface of the coil support body to the receiving coil chamber and through which the connection lines of the receiving coil extend. The connection lines of the sending coil in the first connection bores are shielded from the connection lines of the receiving coil in the second connection bores by the coil support body.
