ABSTRACT:
A three wire potentiometric liquid level sensor for measuring liquid levels in a container is disclosed. The sensor includes a conductive strip, a float, a contact means attached to the float, a resistive strip, and a conductive rod buried beneath an insulator. A second embodiment of the invention includes a first conductive strip, a second conductive strip, a float, a contact means attached to the float, and an insulating rod. The sensor produces a resistance directly proportional to the liquid level in the container.
