ZF-DDK LevelWater-Oil Interface Controller
The ZF-DDK level/water-oil interface controllers use liquid conductivity to detect and control levels, preventing electrode corrosion with AC signals. It offers single-channel for point level control and dual-channel for high/low level or two-tank control. Commonly used in industries like pharmaceuticals, food, water treatment, and chemicals for level alarms and automatic water control in conductive liquids and oil-water interfaces.
