The invention relates to a measurement transmitter for operation in a process plant. The enclosure of the measurement transmitter comprises two mutually separate containers (11, 12), where the transducer for converting the process-related, physical variable into an appropriate electrical variable is housed in the one container (11), and an electronic circuit (22) is arranged in the other container (12). The two containers (11, 12) have complimentary screw threads (51, 52) to each other, and are screwed together directly. The screw connection of the two containers (11, 12) comprises a transformer made up of two parts (31, 32), whose parts (31, 32) each comprise a winding (41, 42) connected to the circuitry (21, 22) of the respective container (11, 12).
