Level switch

Various instruments have found use for applications requiring level sensing. Such instruments include float level switches, ultrasonic level switches and capacitance point level switches. Various devices have been proposed for indicating when liquid or other fluent material in a container or channel reaches a particular level. Liquid level sensors are used in a wide variety of applications to detect the levels of fluids within various forms of reservoirs. For example, such sensors are employed in the automotive industry to sense the level of oil in an oil pan or sump, or the level of transmission fluid. Liquid level sensors contain switches to indicate whether a sensed liquid is above or below a predetermined level. Switches responsive to fluid levels have utilized a variety of approaches for opening and closing an electrical circuit. Fluid level switch devices usually incorporate a float buoy for sensing the fluid level, the float buoy being operatively connected to a switch device.
