Abstract

A cable circuit includes a contactless interface for signal transmission between the cable circuit and the sensor module, wherein the sensor module is galvanically isolated from the cable circuit, and wherein signal transmission between the cable circuit and the sensor module occurs on an optical, inductive or capacitive path. Additionally, the cable circuit includes a signal processing unit, as well as a cable interface for connecting a cable, which connects the cable circuit with the measurement transmitter. The signal processing unit is integrated into the signal path. The signal processing unit is embodied to receive, via the cable interface, signals from the measurement transmitter, to condition them and to transmit them via the contactless interface to the sensor module, and to receive, via the contactless interface, signals from the sensor module, to condition them and to transmit them via the cable interface to the measurement transmitter.
