The Model 780 Hermetically Sealed Level Control is a side-mounted float type liquid level control. This unit is used as a high or low level control. Also, can be used to sound alarms or operate control equipment.

Operation

As the liquid in the vessel rises, lifting the float, a magnet (weld sealed inside the arm) is moved downward toward the hermetically sealed reed switch inside the housing body, causing magnetic actuation of the switch.
