1\/ DIGITAL MEASUREMENT PRINCIPLE
\nThe light source sends light to the interface between a prism and the process solution, where the rays meet the surface at different angles. Depending on the angle, some rays reflex a total internal reflection, while the rest of the light is refracted during processing stage.<\/p>\n
Thus, an optical image with a dark sector and a light sector is created. The angle corresponding to the shadow line is called
\nthe critical angle of total internal reflection. This angle is a function of the refractive index and therefore the concentration of the solution. A CCD-camera detects the optical image. The image is transformed point-by-point into a digital signal. Digital signal processing is used to locate the exact shadow line position and to determine the refractive index nD.
\nA built-in temperature sensor measures the temperature T on the interface of the process liquid. The sensor converts the refractive index nD and temperature T into Brix units. The diagnostics program ensures that the measurement is reliable.<\/p>\n
