Level Switch
Level Switch is a device used for detection and control of point-level for liquids or solids in tanks, silos, and process lines.
Unlike level transmitters, which display the level continuously, this device generates a switch on or off signal only when the material reaches a specified point.
Level switches are widely used in oil and gas, water and wastewater, petrochemical, food, pharmaceutical, and steel industries for protecting pumps, preventing overflow or emptying of tanks, and enhancing process safety.
🔹 Features and Benefits
-
High accuracy point-level control
-
Prevention of pump overflow or dry running
-
Applicable for liquids, solids, and slurries
-
Robust design for harsh industrial environments
-
Diverse options: float, capacitive, vibrating, radar
