Kaidi KDSS86FT 400℃ 1/2'' PF Rotary Paddle Level Switch

Rotary Paddle Level Switch  is a level controller for solid materials (including powder, block, granular, gel, etc.). The motor drives the blade to rotate. When the measured medium reaches the blade position, the blade is blocked and stops rotating, thereby triggering the micro switch to output the switch signal. When the measured medium descends away from the blade, the blade returns to the original position and continues to rotate under the action of the spring. The tension of the spring can be adjusted according to the specific gravity of the measured medium, and the spring with the material ratio is adjusted to the strongest, and vice versa.

The Rotary Paddle Level Switch has been widely used in the chemical, plastic, cement, pharmaceutical, feed, food and other industries.

A unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at 1 RPM. When this paddle rotation is impeded by material, surrounding the paddle, motor will stall and cause the Micro switch to change state. (Indicating an alarm or control) 

The torque spring is applied to adjust the output torque of the shaft, which is set at “weak” position at factory, it is adjustable for target measuring material S.G.(special gravity), if the measured material with higher S.G., please try to release it to more stronger spring force position until you found the proper orientation.

The paddle sensitivity will be interacted by weaker, otherwise, the low S.G. material will release torque spring to the weakest position, which will cause the paddle performance to be more sensitive.

Note: the torque force should not be adjusted during test, avoiding the error check signal.

CAUTION

Make sure the supplying voltage is same as the specifications. Wrong voltage will damage the sensor.

WARNING

To avoid personal injury, DO NOT remove the housing cover after supplying the power. If you will touch any solder joints and terminals, you may receive an electric shock.

Please check that the shaft and the paddle is bended or is damaged; Please check the connect between the shaft and the paddle; Do cleaning the shaft and the paddle timely.

When do installing or maintenance, open the device only after the power source is off.

Please side mount the switch by inclined 15°~20° to decrease the material inflowing impact; The wiring entry face downward, avoid the rain permeate into housing body.
