FLUID IO Teflon vlotter voor vloeistoffen tot 150°C

The float of the QFS-50 and QFS-60 float switches is made of Teflon. Inside the float, one or two reed contacts with a movable permanent magnet are inserted as a switching element.  

The construction of the switching element is designed in such a way that even a slight shift of the switching element from the horizontal triggers the switching process. The switching element is connected via a highly flexible, three-core cable, which is also used to mechanically fasten the QFS. The complete QFS is constructed in such a way that the floating body is hermetically sealed with the cable bushing. The version type QFS-60 is without bellows.
