Rotary Paddle Level Switch, level controller, leve

Rotary Paddle Level Switch is a level controller that is used in solid materials (granular, pelletized and powder bulk applications). It is designed with the features of superior tightness and overloading (overload protection), portable and easy installation, and high contact capacity. The overall contacting section can be stainless steel which can be realized by adjusting the tension of the spring. This switch is widely used in chemical industry, plastic, cement, pharmacy, forage, foot and other industries.The paddles are driven by the permanent-magnet electromotor, when the level ascends to the blades level, the paddles stop rotating, and the resistance is transferred to the detecting device inside the junction box through the transmission shaft. When the level descends, the resistance of the paddle disappears, the detecting device restores to the original status with the tension from the spring, and the paddle rotates again. Provided the density of the solid is high, the tension of the spring shall be adjusted. The tension of the spring shall be adjusted to “Max” when the density is high, and to “Min” when the density is low.
