摘要：
A measurement transducer of a thermal mass flow meter for determining the flow rate of a medium that flows through a pipe, which comprises at least one thin film resistance thermometer, which is arranged in a sheath, wherein the sheath comprises a first open end, out of which at least one cable for electrical contact with the resistance thermometer is led out of the sheath, wherein the cable in the sheath is embedded in a first fill material, at least in sections, and wherein the thin film resistance thermometer is at least partially covered by a second fill material, which is a gaseous, liquid, semi-liquid, powder or solid and in the case cited last, comprises a hardness of at most Shore A 90, and that the first fill material comprises a hardness of at most Shore D 98.
