DescriptionThe "Bent Stem" L090 Float Switch mounts less than 3" into the side of a tank and can detect liquid levels with specific gravities as low as 0.45. L090 material options include stainless steel or Buna-N floats with a selection of brass or stainless steel stem mounts. Various mounting sizes are also available for installation into a mounting boss or directly through the tank wall.
Principles of OperationA hermetically-sealed reed switch is actuated by an internal magnet within the float. As the float rises and falls with the liquid level, the magnetic field passes the switch encapsulated within the stem and causes the contact to either open or close.
