UPF-A teach-in Series
New family of teachable ultrasonic fork sensors for web guide and edge control
The edge sensor type UPF-A TOR is based on the experience of SNT Sensortechnik AG with ultrasonic through beam sensors. New software algorhythms and a unique SONARANGE ultrasonic transducer material allow an accuracy and temperature stability so far only realized with optical systems. But the ultrasonic fork barrier is much less sensitive to dirt and dust compared to optical sensors. Further more transparent materials such as foils can be perfectly handled. The so called plane change error has been minimized to almost zero. Together with the high sampling speed of the sensor this means that fast moving and thus fluttering webs are well aligned.
