Device with a measuring cell for measuring a measured variable of a medium flowing through a measuring cell

A device for measuring a measured variable of a medium, the device comprising:

• a measuring cell through which the medium can flow in a flow direction, the measuring cell including an inner chamber, an inlet channel, which opens into the inner chamber on an inlet side, and an outlet channel, which opens into the inner chamber on an outlet side;
• a first duct extending along a first longitudinal axis and opening into the inner chamber;
• a first component configured to be introduced through the first duct such that a first end portion of the first component extends into the inner chamber at a first insertion depth;
• and
• a first molded part, which:
• surrounds, on an exterior of at least all lateral sides, the first end portion of the first component introduced at the first insertion depth;
• surrounds and delimits a hollow chamber adjacent to an end face of the first component in the inner chamber on all lateral sides;
• and
• includes a recess connecting the hollow chamber to the inlet channel and a recess connecting the hollow chamber to the outlet channel, wherein each of the two recesses is configured as a cross-section converter having a cross-sectional area that continuously and gradually transitions from a first cross-sectional area to a second cross-sectional area in a direction extending from a respective channel to the hollow chamber, wherein the first cross-sectional area corresponds to a channel cross-sectional area of the respective channel adjoining the respective recess, and the second cross-sectional area corresponds to a hollow chamber cross-sectional area of a hollow chamber region of the hollow chamber adjacent to the respective recess.
