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.
