dear sir ..

i am thirumalai i want to some technical information of the water level sensor and how to working principle magnetic type of water level sensors.already make a wire type sensor using for sl100 transistor directly apply to 12volt supply for in bottom level of the tank . so this type based on the electro plating my copper type sensor is corosive . how to prevent the copper sensor so i want idea and neat skitch the drawing .. thanks ..

Dear Thirumalai,

It seems that the conductivity type water level sensor that you designed makes use of DC on probes. This is the cause of electrolytic corrosion. Try using 12 V AC. This will avoid deterioration of the electrodes. A Stainless steel electrode is preferable instead of copper. You may need to modify your circuit to adopt to AC on probe condition.
