Product Features Highly integrated mechanical sealing which prevent infiltration of power along the axle, special paddle can be applied for materials of low density.
Special elastic clutch structure, when the paddle is overhead, it will automatically protect the motor, completely separate mechanic and electrical structure, with no need of dismanting and convenient for maintenance.
Applications Widely applied for manufacturing and processing instruments in fields of food, feed stuff, cement, plastic, processing infrastructure, chemical and chemical fiber industry etc.
Working Principle On the basis that motor drives the paddle to rotate, when the medium measure increases up to the level of the paddle position, the paddle will stop rotating for the obstruction of the medium, then there will output ON or OFF contact signal through related control structure; when the medium decreases lowr than the paddle position, the paddle, under the force of spring, will restore to the normal position to rotate and detect the position changes of medium.
