ri i Die einstellbare Stromquelle LM 3342 von National Semi- conductor läßt sich ohne wei- teres als linearerTemperatur- sensor mißbrauchen. Durch R1 wird der Strom eingestellt, er beträgt beim angegebenen Wert 1 yAlK. Der Stromaus- gang des Sensors ist beson- ders furlängere (mehrere zehn Meter) Zweidraht-Leitungen geeignet, da Kabelwiderstand und -kapazitätkeinen Einfluß auf den Meßstrom haben. jetzt Man benötigt nur noch ein kleines, präzises Strom/Spa n nungs-|nterface als Vorsatz fürein Digitalvolt- meter. Der Meßstrom fließtüber P1 und R2 und soll dort einen Spannungsabfall von 1O mV/K verursachen. C 5 unterdrückt
