Abstract

A measurement transmitter for providing a measured value to a control system, comprising: a sensor having a transducer for outputting a primary signal dependent on the measured value; a first electronic circuit for processing the primary signal to an intermediate signal; a second electronic circuit for processing the intermediate signal to a signal representing the measured value, wherein the second electronic circuit has a signal output for outputting the signal to connection lines; a housing arrangement having a metal material, wherein the first electronic circuit has at least a first circuit carrier, and the second electronic circuit has at least a second circuit carrier, and wherein the first and second electronic circuits are positioned in the housing arrangement spaced from one another. Electrically conducting shielding and high frequency filters for protecting against HF disturbances, which can get into the housing arrangement via the connection lines. The electrically conducting shielding and the high frequency filters are arranged between the first and second circuit carriers.
