Abstract

A measurement device, particularly an anemometric measurement device, is provided for mounting in an exhaust-gas pipe, particularly an exhaust-gas recirculation pipe. The device includes a ceramic carrier embedded in an injection-molded housing made of plastic, with at least one film resistor mounted on the ceramic carrier on an end opposite the embedding. Electrical connections lead out from the film resistor to the embedded end of the ceramic carrier, and the electrical connections are passed through the injection molding, sealed and mounted within the injection-molded part. Additional components can be used for the sealing and mounting.
