SENSOR DEVICE FOR CONDUCTIVITY MEASUREMENT AND METHOD FOR ITS OPERATION

摘要

A sensor device for insertion into a water channel in a washing machine is provided with two electrodes as sensors on a sensor carrier. These electrodes are in direct contact with the water through apertures. The electrodes are connected to a transformer on the sensor carrier directly and without any further components or couplings being required. The other side of the transformer is connected to an activating and evaluating means, in particular to a microprocessor positioned on the same carrier.
