Abstract
The invention relates to a transducer (4) and a method for determining measuring values and for exchanging data between an evaluation device and the transducer which are connected by at least two connecting lines (2B, 2A; 11, 12). Data which is predetermined by the evaluation device is read-out of the data memory and/or rewritten into the same via at least two connecting lines (2A, 2B; 12) which have the same electrical potential in the measuring operation. The data memory is embodied as a data memory module (5) and contains a current limitation circuit (2) by which the system can be switched from the measuring mode to a communication mode for data transfer. The lines (2A, 2B; 11, 12) are thus provided for switching into the communication mode and for exchanging data during the measuring operation, and for feeding the transducer (4) and/or for detecting measuring values.
