Optical sensors
Optical measurement - measurement of weft distortion, patterns, pick count and basis weight
Scanner CTK-15
Imaging scanning (carpet & technical textiles)
Camera sensor for carpet and technical textiles
A high-resolution camera determines the angle of the weft thread of a running textile web. The camera image here is larger than with the standard camera sensor CK.
Product Highlights
- Latest camera technology
- Camera image 90 x 90 mm
- Fixed focus (no product-specific adjustment necessary)
Customer benefits
- Automatic scanning of even complicated fabric structures
- Exact distortion detection for carpets and technical textiles
Distortion detection with camera technology
Several high-resolution cameras placed across the product width scan the passing material web. The angle of the weft thread is determined by FFT analysis.
Interfering signals not agreeing with the frequency of weft threads, courses or rows of tufting are filtered digitally. Only signals relevant to distortion are analysed and the web distortion is calculated automatically and precisely from this.
Suitable lighting versions (refl ex light, transmitted light, power lights) are available also featuring automatic adjustment of the light intensity to different material grades.
