DIGITAL MEASUREMENT PRINCIPLE Critical angle The light source sends light against the interface between a prism and the process solution, where the rays meet the surface at different angles. Prism Reected light Light source The angle corresponding to the shadow line is called the critical angle of total internal reection. This angle is a function of the refractive index and therefore the concentration of the solution. Process medium Optical image Light source DATA LOGGING VIA ETHERNET Refracted light Depending on the angle, some rays undergo a total internal reection. The rest of the light is...
