3 standard model of rotary type level switch that continously keeps evolving. Covering a wide range of applications with various models. Rotary Type C0 Clutch: C0/SK Motor Inner Structure You may easily adjust torque when taking off the id. It prevents powder from intruding from the axis with oilseal and thrust -teflon packing. The clutch system helps prevent the motor from being broken even when the paddle is overloaded. : Bearing Shaft: Oilseal:NBR : Microswitch : id: You may take off interior components as it remains fixed on a tank, and you can easily inspect and service it. You may reliably detect the measuring substance from hypobaric powder to particles with no sensitivity adjustment only if you select the appropriate size of the paddle. Principle Of Operation rotating paddle, being loaded by sediments in a tank, activates a limit switch and brings contact output and motor rotation to a halt at the same time. With no load by sediments, the motor resumes rotation. When the paddle is overloaded or suffers strong shock, a clutch system prevents the motor from being broken by letting out excessive load and shock.

8 Removal of expendable mechanical parts from an internal motor comes up with a long life surpassing other Rotary Type level switches as well as the stability. Reversible Type C0 Clutch: C0/SK Motor Inner Structure It is highly effective in such processes as excessive On/Off operations. Flowing materials to be measured. Fast powder replacement for a small tank. These processes often require the level switch s detecting operations, thus curtailing the life of the motor extremely. These series, however, secure the long life of the motor unit. : id: Microswitch : : Bearing Shaft: Oilseal:NBR Principle Of Operation Utilizing the switching system we developed on the basis of our experiences and accomplishments in the market, it has offered the highly stable and reliable detection regardless of its paddle rotatingdirection. rotating paddle, being loaded by sediments in a tank, activates a micro switch and brings contact output and motor rotation to a halt at the same time. With no load by sediments, the motor resumes rotation. When the paddle is overloaded or suffer strong shock, a clutch system prevents the motor from being broken by letting out excessive load and shock.
