In the coating process, temperature control is required to ensure proper coating adhesion, surface finish, and mechanical properties. With WilliamsonÕs broad product capabilities, it is possible to select sensors that minimize emissivity sensitivity for accurate product temperature control of coated stock. The single-wavelength 4200 and 5200 Auto Null sensors are used for low temperature strip and organic coating applications, while the dual-wavelength 8000 and 9000 Series sensors are used for applications above 400ûF (200ûC). Of particular significance, the multi-wavelength 12200 series sensors are used for nonferrous aluminum, copper, or zinc coating applications. This ability to provide accurate and repeatable measurements of nonferrous surfaces is an exclusive capability from Williamson. The patented 12200 design combines multi-wavelength hardware with a blending algorithm that was specifically developed for nonferrous materials.
