A measuring instrument for measuring a measurand of an object under measurement is provided. The measuring instrument includes a functional member for converting the measurand into a metered value, a housing and an antenna, in which at least part of the housing and/or part of the functional member form a component part of the antenna.

Measuring instrument

The pressure transducer comprises a pressure connection (2) and a tube-shaped housing (22) that is securely attached at its lower end section (24) to the pressure connection. Arranged in the interior of the housing (22) are a pressure sensor (6) carried by the pressure connection (2) and a circuit arrangement (8). An interface module (18) is attached at the upper end section (26) of the housing (22), the connection between the interface module (18) and the upper end section (26) being effected by means of a locking ring (32) that is locked to the housing (22) and that is either integral with the interface module (18) or that carries a union nut (46) that secures the interface module (18) to the locking ring (32). During manufacture of the pressure transformer, the housing (22) is attached to the pressure connection (2) before the interface module (18) is brought into electrical contact with the circuit arrangement (8) and before it is connected mechanically to the housing (22). This makes it possible to adjust the pressure transducer prior to attaching the interface module (18). Furthermore, the pressure transducer can be provided with a plurality of different interface modules without this resulting in disadvantages during manufacture of the pressure transducer. (FIG. 1)
