Device overview
The ultrasonic double sheet testing system consists of a VDB 112 B… analysis amplifier
and a pair of DB 112 UP ultrasonic sensors.
It detects and checks primarily paper, plastic and metal foils which are guided in by feeders.
The device functions as a presence monitor by constantly applying a signal at the
single
sheet
output when an object is located between the sensors. It functions as a double sheet
testing unit by comparing each sheet with the stored reference value. A detected double
sheet is signalled at the
double sheet
output.
