CWG COATING WEIGHT GAUGE
Our coating measurement system can measure continuously and online during process different nature of coatings:
- ZINC
- ZINC AND IRON
- ZINC AND ALUMINIUM
- ZINC AND IRON
Using back-scattering, as for the overall thickness, our coating gauges can be controlled by a PC or a PLC, using pure digital signals from and to sensors. Due to the low level of signal in this kind of equipments, we do use only HDX and HGX sensors, to guarantee a very high precision. Our coating gauging systems had a big positive impact on our Customer's production quality since the first installation. A tight control of coating can be translated into savings, giving exactly the right balance and using the correct quantity of coating material. The system is an x-ray based device for measurement of a specific coating over a metallic substrate. It was designed primarily for a zinc coating over steel, but measurement of other specific coatings, such as tin, are possible. The system is a non-contact device that relies on x-ray florescence of the substrate (steel), and measures the attenuation of the resulting radiation through the coating. It consists of a sensor head, an application specific scanning frame, a local control cabinet (LCC), a fiber optic communication link, and a computer cabinet (EPC). Gauging parameters such as set thickness, range, limits, etc. can be entered from the local operator's computer (at the EPC) or from a host computer/PLC (using protocol). The Coating Weight Gauge operates on an industrial computer system for improved reliability, however, it can also run on a commercial grade PC that has an ethernet port and two USB ports. All necessary settings are stored on the local hard drive, and will be automatically reloaded when the software is restarted.
