Abstract

Sensör bağlantı uçları bulunan bir sensörü (1) içeren bir sensör düzenlemesi olup, en az bir sensör (1) en az 1,1 Lüks ışık aldığında bir sinyal sapması üretmek üzere ve 1,1 Lüksten daha az ışık aldığında eşit sinyaller üretmek üzere yapılandırılmıştır, bir diferansiyel amplifikatör (2), giriş kanallarına uygulanan sinyal sapmasına karşılık çıkış kanalında (3) bir akım üretmektedir, bir yük öğesi (6), çıkış kanalında (3) üretilen akımın bir fonksiyonu olarak bir ilk güç miktarını yaymaktadır, diferansiyel amplifikatör (2), sensör (1) tarafından giriş kanallarına uygulanan sinyal sapmasına karşılık besleme bağlantı uçlarından (7, 8) bir ilk yük akımını çekmektedir, diferansiyel amplifikatör (2), giriş kanallarına (-, +) uygulanan eşit sinyallere karşılık besleme bağlantı uçlarından (7, 8) ikinci bir sakin akımı çekmektedir.A sensor arrangement comprising a sensor (1) with sensor connectors, configured to generate a signal deviation when at least one sensor (1) receives light of at least 1.1 Lux and to produce equal signals when receiving less than 1.1 Lux, a differential amplifier (2) generates a current in the output channel (3) in response to the signal deviation applied to the input channels, a load element (6) emits an initial amount of power as a function of the current generated in the output channel (3), the differential amplifier (2) The differential amplifier (2) draws an initial load current from the supply terminals (7, 8) in response to the signal deviation applied to the input channels by the sensor (1), from the supply terminals (7, 8) in response to equal signals applied to the input channels (-, +). ) draws a second quiescent current.
