Abstract

A sensor device for detecting a property of a fluid medium flowing in a channel includes: (a) a channel piece through which a fluid medium is able to flow, the channel piece having (i) an inlet; (ii) an outlet; (iii) a channel piece wall including an inner wall, an outer side connecting the inlet and the outlet, and an insertion opening; and (iv) areas having electrical conductivity; (b) at least one sensor having a sensor housing and a sensor element situated in the sensor housing, the sensor housing being insertable through the insertion opening in the channel piece wall into the channel piece. The entire channel piece wall of the channel piece is completely made of electrically conductive plastic, the channel piece wall being at fixed electrical potentials.
