The first step was to evaluate the location and design a scanning solution using near infrared (NIR) to measure the cross-web distribution of coating thickness. The coating application employs a solvent-based coating, so the system was designed to operate within and meet all specifications of a C1D1 classified area. We provided one of our standard scanning frame solutions to meet the customers’ needs.
The next step involved dealing with the existing nuclear gamma-based sensors. Quad Plus gauging offers the service of removing and disposing of nuclear-based sensors. This is carried out safely and in compliance with all national and state regulations. Quad Plus is trained and authorized to service and remove nuclear based sensors.
Once the system was installed and providing reliable, fast, and accurate measurement data, we implemented closed-loop control of the customer’s roll gap, which is used to control the coating thickness. This was accomplished by evaluating the existing electrical system in place and recommending any necessary changes. The mechanical machine geometry was also assessed, and the control scheme programming was designed to account for it. The implementation of roll gap control provided operations with the reassurance that their product would meet specifications and no longer require constant operator monitoring.
