Keep the correct parts level in the bowl by SDVC34 vibratory feeder controller without parts level sensor
In some case, the automatic feeding system include hopper, feeder bowel, in line feeder and robot arm. when the feeder bowl is empty or below the parts level which you expect in the bowl, you need to feed it manually or automatically from hopper. Most situation you should use the parts level sensor to see whether the bowel is empty or not, but our controller can help you to achieve it without level sensor and the level expected can be adjusted by parameter in the controller. In addition when the feeder bowel is empty or below the level that you expect, the controller will give a 24V DC signal that could enable the alarm light bulb, the hopper or other automatic devices.
THE PRINCIPLE OF DETECTING THE PARTS LEVEL
The controller can stabilize automatically the feeder speed by vibration sensor. when the amount of parts in the bowel is decrease, the power output voltage will be decreased for keeping the constant feeder speed, so we can know the parts level in the bowl by the power output voltage.

The threshold value, the lowest parts level in the feeder bowel, can be adjusted by the parameter "GL" in the controller.
PROCESS OF KEEPING THE CORRECT PARTS LEVEL
The video will show the process of the feeder automatically.
