Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zur Bestimmung eines Füllstandes und einer Temperatur eines Fluids. DOLLAR A Um eine noch kompaktere Vorrichtung und ein effizienteres Messverfahren bereitzustellen, wird vorgeschlagen, dass der Heizdraht (21) eine PTC- bzw. Kaltleiter-Charakteristik aufweist und mit einer Auswerteschaltung durch Spannungsmessung bei Strombeaufschlagung als Füllstandssensor und zugleich als Fluidtemperatur-Sensor ausgebildet ist.
