Float Switch - FLS
Brand: WIKA Alexander Wiegand SE & Co. KG
A float with a permanent magnet moves reliably along with the liquid level on a guide tube.
Within the guide tube is fitted a reed contact (inert gas contact), which is energised, through the non-magnetic walls of the float and guide tube, by the approach of the float magnet. By using a magnet and reed contact the switching operation is non-contact, free from wear and needs no power supply.
The contacts are potentialfree. Float switches are also available with multiple switch points.
