Abstract (en)
[origin: WO03050480A1] The invention relates to an electronic field device with a sensor unit (2), for capacitive level measurement in a container (3), whereby the electronic field device is connected to the sensor unit (2) by corresponding signal paths. The electronic field device generates a voltage signal for operation of the sensor unit (2) and receives and analyses a measuring current from the sensor unit (2). According to the invention, an analogue/digital converter (8), for digitising the analogue measuring current, a microprocessor (1) and a memory unit (7) are provided, whereby the microprocessor carries out the generation of the voltage signal, the analysis of the measuring current, a compensation for interference and a determination of the recorded parameters for the sensor/container arrangement, according to given programme sequences and the corresponding programmes are stored in the memory unit (7).
