COMPACT SENSOR FOR SMALL PIPES PROBE SENSOR FOR LARGE PIPES AND VESSELS Pipe bend Large pipe K-Patents Sanitary Process Refractometer PR-23-A sensor is factory calibrated to measure refractive index nD and temperature T in standard units. Each sensor has identical calibration nD=1.31...1.54 (corresponding to 0-100 Brix). The non-linear conversion from refractive index to Brix or concentration units and also temperature compensation are based on standard tables. They are programmed inside the transmitter independently of the sensor. Therefore, all sensors are freely interchangeable. To keep velocity...

DIGITAL MEASUREMENT PRINCIPLE Light source The measurement accuracy is not influenced by particles, bubbles, sugar crystals, seeds, fibres, colour or temperature changes in the process medium. Critical angle Process medium 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 Reflected light The angle corresponding to the shadow line is called the Critical Angle of Total Reflection. The Critical Angle is a function of the refractive index and hence the con­­cen­tration of the solution. Light Source Refracted...
