Abstract: Two embodiments of an analog liquid level sensor are provided for measuring the level of a liquid in a container having a volume/depth relationship wherein each sensor has a resistance-to-float-displacement profile matched to the volume/depth relationship of the container. Each sensor includes a dielectric coated metal bar which acts as a heat sink and a ground plane. A pair of electrically spaced terminals and a printed circuit including a thick film resistor pattern and a metallization pattern having metallized graduations are formed on the metal bar for reduced electrical noise characteristics and improved hysteresis. The resistance of the resistor pattern is electrically coupled between the terminals and has a resistance which varies at different positions between the terminals. The metallization pattern is formed on the resistor pattern which, in turn, is formed on opposite sides of the dielectric coated metal bar.
