WIKA

FLS Magnetic Float Switch

In the WIKA FLS magnetic float switch 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.

Price and delivery time will be given on request
Operating temperature -196 ... +350 °C
Operating pressure Up to 40 bar
Limit density ≥ 300 kg/m³
Ingress protection IP 66 or IP 68 (depending on version)

In the WIKA FLS magnetic float switch 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.

The switching functions always refer to a rising liquid level: Normally open, normally closed or change-over contact.

Through the use of a float for a max. of 2 switch points a bistable switch behaviour can be achieved, meaning that the switching status also remains available, when the filling level continues to rise above or drop below the switch point.

The float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low.
