Functional description

UD ultrasonic groove sensor is used to identify the printing
mode of labels and carrier materials, and the materials with
transparency and surface roughness, and can identify whether
the materials are one layer or two layers. Such as transparent
labels on transparent carrier materials and different printed
patterns on the labels.

UD ultrasonic groove sensor can identify the labels with the
minimum spacing of 2mm, and it has high positioning accuracy,
short response time and small size, which makes the groove
sensor widely used.
