发明名称 Liquid level sensor with conductive torsion springs
摘要 An assembly with liquid level sensor probes which rotate down into a container by means of torsion springs, thereby eliminating failure to the springs due to bending. The torsion springs also act as conductors in an electric circuit without any electrical slip joints or rotating electrical contact joints which can become contaminated or oxidized and thereby interrupt electric continuity of the circuit.
