Point level sensors for top down mounting
LI level sensors are used to monitor minimum levels, overflow or leakage of tanks. They are suitable for water, oils and coolants. The intuitive operating concept allows the user to easily perform an empty or full adjustment and configure the output function - all at the touch of a button. The sensors are available with four different probe lengths. The immersion depth is easily adjusted using the optional screw-in or flange adapters. The LI21 series is approved to the German Federal Water Act (WHG) section 19.
Features & Benefits
- Clearly visible indication of the switching status
- Easy pushbutton adjustment in the application
- Modular concept for a large variety of applications
- Versions with overflow prevention to Federal Water Act WHG § 19
