Abstract: A measuring transducer for registering and/or monitoring at least one process variable of a flowable medium guided in a pipeline, which at least includes: a housing module, which is mechanically coupled with the pipeline via an inlet end and an outlet end, and a sensor module having at least one measuring tube held oscillatably at least partially in the housing module and caused, at least at times, to oscillate. The at least one component of the housing module and/or of the sensor module is manufactured by means of a generative method and method for manufacturing at least one component of a measuring transducer, which method includes manufacturing the at least one component by means of a primary forming process, especially by means of a layered applying and/or melting-on of a powder, especially a metal powder, based on a digital data set, which gives at least the shape and/or the material and/or the structure of the at least one component.
