Abstract
A probe for measuring the level of a liquid and its method of manufacture are disclosed. A conducting circuit whose resistivity depends on temperature comprises a track applied to a substrate in which is formed a window which leaves free an appreciable length of track, so that its behavior is not disturbed by the presence of the substrate. The conducting circuit is partially immersed in the liquid and the voltage at its terminals is measured when a constant current flows therethrough. The voltage measurement is representative of the level of the liquid.
