The capacitive filling level probe NC56 serves to measure tank filling levels in plastic and métal tanks containing
• – Fresh water
• – Waste water, faeces
• – Diesel fuel
• – Extinguishing foam
Filling level heights of between 400 – 2000 mm can be measured.
Design and mode of operation
An AC voltage signal is exerted onto two métal rods held at a defined distance to each other. When dipped into fluids, these métal rods become a ca-pacitor within an electrical circuit.
The capacitive values of this capacitor are primarily determined via the filling level height and the result-ing change in the dielectrics.
Electronics integrated into the device convert these capacity changes into linear electrical uniform signais 0…20 mA / 4 .20 mA / 0…10 V DC / 0…5 V DC /1…5 V DC / 2…10 V DC um.
