Mini Rotary Paddle Level Switch RT10

Product Profile：

Rotary Paddle Level Switch is a level controller that is used in solid materials (including powder, grain, mass and colloid). It is designed with the features of superior tightness and overloading (overload protection), light weight 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.。

Working Principle：

The blades are driven by the permanent-magnet electromotor, when the level ascends to the blades level, the blades 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 blade disappears, the detecting device restores to the original status with the tension from the spring, and the blade 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 “highest” when the density is high, and to “lowest” when the density is low.。

Notices for installation:

1. If the temperature inside the barrel exceeds 80℃，please use the high temperature series products.
2. The opening of the junction box shall face downwards, the fixing nut must be tightened.
3. When connect the part with thread “1”, the falcate blades can be used in order to lock to the solenoglyphic tooth directly.
4. when it is mounted on the side plate, the controller level shall be 15°～20°to the horizontal plane to minimize the impact on the material.
5. Type RT50 and RT70 can be top-loaded only.
6. When necessary, a copper plate can be welded above the bulkhead to reduce the impact of the product on the material.
