  • Sensor assembly for a radiator mounted coolant level monitoring system
    Patent number: 4638291
    Abstract: An electrically conductive liquid level sensor utilizing a pair of parallel closely spaced electrically conducting probes that are exposed within a liquid container for immersion in said liquid. The sensor includes an electrical insulator partition extending between the probes so as to interrupt any direct path therebetween while at the same time localizing the conduction path to a narrow band of liquid levels due to the close spacing of the probes.

  • Liquid level sensor switch
    Patent number: 4467156
    Abstract: A liquid level sensor switch to indicate whether a sensed liquid is above or below a predetermined level utilizing a generally cylindrical float element that is slightly ballasted along its length so that it is self-orienting with respect to the vertical. Electrically connected contacts are placed at opposite ends of the ballasted float element and are maintained in a proper downward orientation so as to connect and disconnect an electrically conducting path when the liquid level changes about a predetermined level.
