US SEN 3xx – Ultrasonic sensing for variable web widths
US SEN 3xx
Description
BST US SEN 3xx series ensure accurate and stable edge seeking, even when web widths vary. Ultrasonic waves measure web positions contactlessly, wear-free, and with minimal maintenance requirements.
Thanks to its large proportional measuring range, US SEN 3xx can be used without mechanical repositioning, even with significant width fluctuations. Which is an advantage in flexible production processes and frequent format changes.
The sensor is insensitive to material transparency, dust, and external sound interference, ensuring consistent performance in challenging conditions. Its robust design and simple integration via the BST CANbus guarantee stable signals, easy setup, and long-term operational reliability.

Get to know our web guiding solutions
BST sensors detect the exact position of webs, ensuring stable and efficient web guiding. Whether optical, ultrasonic, or infrared, the sensors reliably detect web edges, web center line, contrast, lines or objects regardless of material or speed. Their fast response and robust design provide the foundation for high process reliability and minimal waste.
BST sensor technology – The foundation for stable processes, precise web guiding, and outstanding product quality.
Our sensors enable you to detect web edges or objects with high precision acoustically, optically, or camera-based. They benefit from stable processes and easy integration. A special feature is the plug and play technology, which makes retrofitting and upgrading particularly easy.
