Abstract

The disclosure includes an inductive conductivity sensor for measuring the specific electrical conductivity of a medium with a transmitter coil energized by an input signal, a receiver coil coupled with the transmitter coil via the medium, which receiver coil supplies an output signal that is a measure for the conductivity of the medium, and a housing enclosing the transmitter coil and the receiver coil, which housing comprises at least one housing section designed to be immersed in the medium, the housing wall of said housing section surrounding the transmitter coil and the receiver coil. The housing is made of a magnetic plastic or resin for inductively decoupling the transmitter coil from the receiver coil. In certain embodiments, the housing may be made of a ferromagnetic material. Another aspect of the disclosure includes a method for manufacturing the conductivity sensor.
