SR Series Rotary Paddle Type Level Switch
Working Principle
Making use of the motor to bring the blade revolving, when the medium rises to the blade position, the blade stops rotating because of the impediment of the medium, thus through the related control mechanism outpus open (on) or close (off) the contact signal; when the medium drops and leaves the blade, under the force of spring, the blade restores the beginning position to go on rotating and detect position change.

Features
Detection of loose solid materials using the technology of the rotating blade;
The highly integrated mechnical seal to prevent infitration of dust along the axis;
The unique elastical clutch structure when overload blade, the automatic protection of electrical machinery;
Completely mechnical and electrical separation structure, need not to demolish wholely, easy to maintain;
Special blades can be used for low-density mediums;
Use of the process connecting pieces, easy to install
