Product Introduction
The ultrasonic sensor in a web guide system is a edge or centering detect sensor used to measure the lateral position of a moving web (paper, film, foil, label stock, etc.) so the guide controller can correct the offset.
Features
Ultra-Fine Resolution
Adopts digital signal detection chip with a resolution of up to 0.0085 mm, featuring high linearity and real-time offset display
Ruggedized Construction
Full aluminum alloy shell provides protection against dust, moisture and smoke, with strong anti-interference capability
Intelligent Surface Sensing
Automatically calibrates detection based on ambient conditions, unaffected by ink marks, labels or color variations
Versatile Design Options
Customizable micro and wide-detection-range sensor available upon request

Drawing
Detection modes
Edge guiding (most common)
- Detects one edge of the web
- Used in unwind, process, or rewind sections
Center guiding
- Uses two ultrasonic sensors
- Calculates the web center automatically
- Useful for variable-width webs
Usage Notes
- It is highly recommended to use SURMACH's free sensor fine - tuning bracket in conjunction with the system.
- Suitable for scenarios where the photoelectric sensor fails due to material transparency.
- Not suitable for fabrics with large pores, soft textures, or fluffy structures.
- Not suitable for environments with significant mechanical vibration, high-speed airflow, or other acoustic interference.
