日本Kansai关西电容式液位开关ALN-111-1 (B33) Capacitance Type Level Switch ALN/ST Series The capacitance type level switch detects level of any kind of materials (powder, granule, lump, liquid, paste, bubble, etc.) More than 1,000 types of electrode shapes and special circuits are available to cover many different applications. Features Highly sensitive and stable. Excellent mechanical strength and durability. Stable detection even with contamination or deposits on electrode. Applicable to highly conductive materials. Easily detects highly corrosive materials. Operating Principles It detects the variations of capacitance between main electrode and tank wall or grounding electrode. As the level in the tank rises, the capacitance value increases, which makes an output contact when it exceeds the preset value.
