2. LC80 APPLICATION EXAMPLE
There are various applications for this type of cameras. One the common applications is the width measurement of web (Textile, Belt, Tread, Side Wall, Inner Liner, …). In this type of application, LC80 is installed on top of the web and a light is inserted below it. The camera can detect the edges of the web and the software computes the width of the web by some mathematical computations and linearization. This computed width can be used in industrial PLCs by OPC.
ViSys LC80 application in width measurement
Also LC80 can be used for detecting several edges. For example, it can be used for measurement of two or three ribbons of films or webs.
