The Proscan ChannelTrak was designed to measure continuously fed web materials, to accurately characterise the surface texture to within 0.5 microns. Applications include thick-film materials, coated metal products, photovoltaics and fine tolerance sheet metals. A pair of high precision rollers present the web material to the confocal chromatic sensor with a wrap of 30 degrees. This allows the measurements to be taken whilst the material is supported by the precisely ground main roller. A full suite of analysis tools are available which can be supplied to suit your specific application. The system scans in real-time and is probably the most accurate on-line non-contact measurement device available anywhere in the world.
