Abstract: A potentiometric sensor, comprising: a potentiometer track; a collector track opposite the potentiometer track; a conductive magnetic cushion slider coupled to the potentiometer track and the collector track; and a sealed body housing the potentiometer track, the collector track, and the conductive magnetic cushion is disclosed. The potentiometric sensor may provide a variable output voltage indicative of a level of liquid in a container. The output voltage of the potentiometric sensor may be based on a position of a magnet, which may determine a position of the conductive magnetic cushion or a ferromagnetic spring.

As the sensor will be more cost effective and less space consuming, the totally sealed sensor incorporating the conductive magnetic cushion or a ferromagnetic spring may replace many applications that allow a hysteresis of less than 1 mm. Additionally, these applications may be used on rotary systems.
