摘要：The invention relates to a sensor and evaluation system for capturing data at ameasuring station (3), in particular for use in double sensors for determining endpositions and limit values. The individual sensors (1, 1', 2, 2', 16, 16') are operated assensor pairs (1', 2', 16') by a largely shared control circuit consisting of two connectinglines (5, 6) with an electric current or voltage of alternate polarity. A state of a sensor (1,1', 2, 2', 16. 16') is transmitted on the corresponding half-wave of the sensor current andevaluated by a switching amplifier (13) in relation to polarity and amplitude. Said sensorand evaluation system reduces the number of connecting lines required. In addition,interference from neighbouring sensors is largely excluded, so that sensors can bemounted more closely together in a system. Said sensor and evaluation system isespecially suited for equipment required to comply with the DIN 19234 (NAMUR)standard.
