The maintenance-free level switch is used for monitoring the level of liquids in open or closed, pressureless tanks. It is nearly insensitive to external interferences and resistant to non-flammable hydraulic liquids.
Construction and Function:
The inserted permanent magnet in the float actuates contact less monostable dry reed contacts. The contacts are fitted on a rail inside the float guide tube, marked in cm an are adjustable in height (min. space of the contacts min. 90 mm). After release of the adapter sleeve a fine-adjustment is also possible by pushing forward of the immersion tube in a longitudinal direction.
By turning the contacts 180° each can be converted from a normally open contact to a normally closed contact or vice versa.
For a tank with turbulent flow a smoothing pipe for the float can be delivered if requested.
