Abstract

For a conventional 2-conductor communication connection, which includes a sensor, a measurement transmitter and a control unit, an isolation unit is provided, which serves for transmission of digital signals, which are not transmitted by the measurement transmitter. Thus, in the case of a conventional 2-conductor communication connection, digital communication between the sensor and the control unit becomes possible.
