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 ).
