Product Overview


Product Overview

Rotary level sensor switch
The operating principle for a rotary paddle switch is straightforward. A unit consists of a motor assembly and a shaft with a paddle attached to the end of it. Typically, a paddle is mounted through the wall at the top, middle or low level of a bin. The
positioning depends on the requirements of the particular application. Rotary paddle technology has been in use for many years, providing point level indication and bin level switching in many industries.

Specific gravity


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)

Modle Selection Guide

Torque Adjust Mechanism

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.

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

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.
