X-Ray Fluorescence Gauges are used to measure coatings containing quantities of metal or heavy elements, on plastic or paper substrates. The sensor energy level is selected for the application, such that the photons striking the material cause it to fluoresce. The returned fluorescence energy provides the information necessary to precisely calculate the coatweight. This selective technique has significant advantages in simplicity of operation, accuracy, and reduced equipment costs.
X-Ray Sensors offer a number of advantages over beta and gamma sensors, including greater precision, better streak detection, long-term stability and non-nuclear technology.
Since the X-ray sensor's energy output can be changed via digital power regulation, it can be optimized to run very efficiently over a wide range of product weights and thicknesses.
