Web-edge-sensor, reliable web and edge guiding ensures a continuous flow of product through machine processes, minimizes downtime, and prevents material damage and loss. sensors are frequently used to monitor and control webs by measuring the web as it travels on the line.. Figure 2: u-shaped edge sensor based on blocking principle the new sensor technology with the light scattering and patented fiber optic sensing principle provides a true, absolute, precise, and digital position measurement of the web. the optical fiber optics act as filter that allows only the light signal that is in direct line with the fibers., the bks ultrasonic edge sensor is a fork sensor for scanning the edges of sound-impermeable materials such as foil or paper. this is why the bks is ideally suited for the web control of highly transparent foils, light-sensitive materials, materials with greatly varying transparency and paper subject to high paper dust loads..
The new sensor technology with the light scattering and patented fiber optic sensing principle provides an accurate web edge or web position measurement. the fiber optics act as a spatial filter that allows only the light signal that is in direct line with the fibers., the bks+ edge sensor facilitates the contact-free web edge scanning of foils, paper and other soundimpermeable materials..
Photoelectric sensors for web edge control from led light arrays to the laser light array edge detection control is a typical application for light array sensors position measurements of the object edge – generally of fast-moving film-like or woven roll material – are used to control the drives and feed mechanisms in production equipment., edge guide sensors (or web guide sensors) are used to detect the position of a moving web and include edge and line sensors. sensor types include infrared (ir), photoelectric, ultrasonic, digital, and pneumatic sensors..
Edge guiding the optical paper edge detection system is capable of regulating a web with an accuracy of approximately 50 μm. the at20 array sensor works according to the scanning principle and therefore does not require a reflector. mounted above the paper web, it is not susceptible to contamination., web edge measurement independent of radial runout, color or surface, edge detection with wide measuring field or of transparent objects as well as lap stream copy counting.. The se-38 first*edge sensor is an all-digital web sensor specifically designed or materials with varying opacities. such voids, common with spun bond and loosely woven materials, are often... fife se-42 infrared light sensor the se-42 sensor uses modulate infrared light.
