NIVOMAG MK-200 series magnetic float level switches are used for point level detection and level control of liquids in all types of vessels.. Measurement principal: a non contact coupling system is realised by the permanent magnet of the float placed in the tank that can activate the microswitch situated in the housing mounted on the outside. The great variety of both the top and side mounted versions makes it easy to install the switch in any tank at any location. For the simplest level switching you can select models with fixed hysteresis, while for level control application we offer Nivomag switches with adjustable hysteresis. Models with rubber or silicon sleeves can be applied for contaminated liquids. You can fit the Nivomag switch with an MMK type tester, to check the switching function even when the liquid levels aren’t changing.
