Capacitance Type Level Switch ALN/SL Series
Operating Principles
It measures the capacitance variations between the main electrode and the tank wall or the main electrode and the grounding electrode. As the level rises, the capacitance value increases, and the contact is output when it exceeds the set value.
The capacitance type level switch detects level points of whatever kind of substances (powders, granules, lumps, liquids, pastes, bubbles, etc.). More than 1,000 types of electrode shapes and special circuits are available for various applications.
- It has high sensitivity and stability.
- It has excellent mechanical strength and durability.
- It stably detects even extraneous matter and deposits.
- It can also be used for highly conductive substances.
- It can easily detect highly corrosive substances.
- Certified with NEPSI (explosion proof regulation China).
- Powder
- Granules
- Liquid
- Surface Interface
- Bubble
