Method for producing a measuring device (1-4, 57) which serves to detect a fluid variable, wherein the fluid variable relates to a fluid which is received or guided in a fluid volume delimited by a measuring duct, and/or relates to a fluid flow of this fluid, wherein a transducer housing, in the interior of which is disposed a vibration transducer (8, 9), is disposed in an interior of the measuring duct that comprises the fluid volume; wherein the transducer housing is connected to the measuring duct in that a connection means is inserted into a through hole of the measuring duct, on the one hand, and is inserted into an opening of the transducer housing, on the other hand, in such a manner that at least one feedthrough of the connection means that connects an exterior lying outside the measuring duct to the interior of the transducer housing is sealed in a fluid-tight manner in relation to the fluid volume, wherein, conjointly with or after inserting the connection means into the opening of the transducer housing, or as a sub-component of the connection means, at least one electrical conductor, which is routed through the feedthrough and by way of which a respective electrical contact of the vibration transducer (8, 9) is contacted so as to connect the latter to a control device of the measuring device (1-4, 57) that is disposed in the exterior, is inserted into the interior of the transducer housing, characterized in that the respective conductor is connected to the respective electrical contact in such a manner that the conductor and the electrical contact are pressed onto one another by a pressing element (26, 27) which is disposed in the exterior or extends through the or a further feedthrough of the connection means from the interior of the transducer housing into the exterior. wherein a transducer housing, in the interior of which is disposed a vibration transducer (8, 9), is disposed in an interior of the measuring duct that comprises the fluid volume; wherein the transducer housing is connected to the measuring duct in that a connection means is inserted into a through hole of the measuring duct, on the one hand, and is inserted into an opening of the transducer housing, on the other hand, in such a manner that at least one feedthrough of the connection means that connects an exterior lying outside the measuring duct to the interior of the transducer housing is sealed in a fluid-tight manner in relation to the fluid volume, wherein, conjointly with or after inserting the connection means into the opening of the transducer housing, or as a sub-component of the connection means, at least one electrical conductor, which is routed through the feedthrough and by way of which a respective electrical contact of the vibration transducer (8, 9) is contacted so as to connect the latter to a control device of the measuring device (1-4, 57) that is disposed in the exterior, is inserted into the interior of the transducer housing, characterized in that the respective conductor is connected to the respective electrical contact in such a manner that the conductor and the electrical contact are pressed onto one another by a pressing element (26, 27) which is disposed in the exterior or extends through the or a further feedthrough of the connection means from the interior of the transducer housing into the exterior.
