DescriptionThe L312B Remote Chamber Level Switch is a compact, level monitoring device designed for installations where internal tank mounting is impractical or impossible. Encased in its own metal float chamber, the L312B can be mounted on the exterior of a tank and supported through pipe connections. The switch and float mechanism are easily detached from their chamber for cleaning and maintenance procedures. Material options include brass or stainless steel mounts paired with a buna or stainless steel internal float.
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.
