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