Yokogawa Electric Corporation announces that it has developed the WG51S2 infrared sensor for the WEBFREX NV online thickness gauge. Positioned as an OpreX™ Quality Control System family solution, the WG51S2 infrared sensor enables the WEBFREX NV online thickness gauge to measure and control the thickness of films and sheets with greater accuracy than ever before. This new product will be released on September 3.
Thickness gauges are used on film and sheet production lines to measure and control film and sheet thickness. They ensure that all products coming off the line are of uniform thickness. Various kinds of plastic film have been developed for packaging, including highly functional film that can preserve the quality of packaged contents and film that can be printed with vivid colors to improve the attractiveness of the packaging. Environmental concerns have driven efforts to make plastic films recyclable and thinner, and so it is important to have thickness gauges that are capable of measuring the thickness of thin films with a high degree of accuracy. To satisfy this need, Yokogawa has developed this infrared sensor.
For the handling of various kinds of films and sheets, four different types of noncontact sensors are available for use with the WEBFREX NV online thickness gauge. These are a β-ray sensor that can measure a wide range of materials, an X-ray sensor that is suitable for measuring compositionally homogeneous films, an infrared sensor that is suitable for use with plastic films that absorb infrared light, and an optical sensor that is suitable for measuring multilayer films and other kinds of transparent films.
