The probe is used for sensing the fill level at 4 stages in water or other conductive liquids. The probe has five hanging electrodes, which hang out at different lengths inside the medium up to the switching point of that stage. The hanging electrodes are in the form of corrosion protected stainless steel weight (plumb), which are hung up with stainless steel rope. When the fill level in the container rises up to the electrode, it gets wet and the presence of medium is registrated due to its conductivity. Because of its flexible constructional arrangement, the electrode length can be individually set at desired switching points. The set contains 10 m of stainless steel rope, so that each probe can be made with over 2 m length.
