Application
This series of electromagnetic level switches has been designed to check the minimum or maximum level of a fluid in a tank and send an electric signal to a remote board in case the fluid goes over or under the set levels. They should be fixed vertically on the cover of the tank, with the float at least 50 mm far from metal walls.
