US TRANSDUCER FOR AIR AND GAS FLOW MEASUREMENT AND A METHOD FOR THE MANUFACTURE THEREOF

摘要

A US transducer for air and gas flow measurement has a cast transducer core formed of a castable damping material which is placed into a core mold. The transducer core is formed of a piezoceramic wafer whose thickness is partially exposed at one side of a damping member, and is composed of the damping member in which the piezoceramic wafer is partially enclosed with leads that can be guided toward the outside. The transducer core is enveloped with a castable adapter material in a bipartite mold for the formation of an adapter and assembly member.
