MEASURING TRANSDUCER FOR A MULTI-SENSOR SYSTEM, IN PARTICULAR AS A FIELD DEVICE FOR PROCESS AUTOMATION TECHNOLOGY AND METHOD FOR OPERATING THE MEASURING TRANSDUCER

摘要

The invention relates to a measuring transducer for a multi-sensor system, in particular as a field device for process automation technology, comprising a processor (1) which is used to process input and output signals and which is connected to an interface (8, 13) to which a sensor (2, 3, 4) for transferring data by means of a transmission line (5, 6, 7) is connected. Data is transferred at different rates for the communication between the processor (1) and the interface (8, 13) or the sensor (2, 3, 4) and the interface (8, 13). In order to connect a plurality of sensors working at different working principles to the measuring transducer, to greatly prevent errors during the transmission of data, despite the plurality of sensors, at least two sensors (5, 6, 7) are provided. The interface (8, 13) for each sensor (5, 6, 7) comprises a function module (9, 10, 11) which is associated with said sensor (5, 6, 7) and the function module (9. 10, 11) associated with the sensor (5, 6, 7) is connected to the respective sensor (5, 6, 7) by means of a respective separate transmission line (5, 6, 7).
