Ultrasonic sensor applies the principle of high frequency ultrasonic linear transmission to detect the edge of the material, comparing to photoelectric sensor, it will not be affected by the transparency of the materials. Thus it is very convenient and no need to adjust. It is suitable for edge application of opaque material (such as plastic film, paper etc¡ and transparent material, such as cloth, but not for non-woven fabrics.).
Ultrasonic sensor feature:
1. Support analogue /on-off output, can match with EPC-A10 or
EPC-D12 web guiding controller to use;
2. Suitable for edge-tracking application of opaque, transparent and
ultra-transparent film and line-tracking ultra-transparent thin film;
3. No need adjustment and calibration manually;
4. 200K ultrasonic correlation;
5. 0.05 mS response time;
6. Detecting range: 6 mm, detecting precision: 0.05 mm;
7. With own offset display.
