Fresh cut flowers that are shipped internationally in large quantities, must be fresh, but still efficiently processed and packaged very gently. In this flower-packing machine it has to be detected when a bunch of flowers is ready in the tub for packing. An ultrasonic sensor of the UPR series (see circle) looks down from above on the flowers and outputs a “present / not present” signal. The ultrasonic sensor was chosen because it is able to detect the very different shapes, colors and textures of the flowers reliably.
 
Why ultrasounnd?
  • independent of material, surface, colour, size
  • works under dust, dirt, fog, bright light
  • detects transparent and shining objects
  • wide measuring ranges from few mm up to 5m
