Ultrasonic sensors assist in packing of fresh flowers
	14 July 2011
SNT Sensortechnik AG: 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 ultrasound?
- 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
