Level gauge switch
The ABB LMS100 SPDT switch is mounted on a level gauge with a magnetic coupling action that eliminates process contact and the need for seals, diaphragms, springs or torque tubes; it senses high or low levels within a vessel. A form C reed switch within the unit is activated via a rotating permanent magnet.
