1. GENERAL INDTRODUCTION, OPERATION
NIVOFLIP MAK-100-type magnetic level switches are suitable for level switching of variuos liquids.
MAK-100 type magnetic level switches are used for magnetic-lamella bypass level indicator (named
NIVOFLIP) as an optional level switch.
OPERATION PRINCIPLE:
Mounted on suitable connection flanges on the side of the tank the liquid level in the bypass tube and the
tank is equal. In the stainless steel bypass tube a magnetic float tracks the level of the liquid. In the float
a permanent magnet is incorporated, which operates the MAK-100 type adjustable positioned magnetic level
switch through the stainless steel side of the tube, and provides non-contact signal transfer to the
microswitch.
Electronic connection is performed with cable gland, wired with a maximal 2.5 mm2cross sectioned cable.
Installation of the level switch is made by 2 pieces of hose clamps. Position of the switch can be changed to
adjust the needed switching level. The level switches are available in normal and Ex versions.
