Suspended Solids and Turbidity Sensors - 1

• Immersion and hygienic sensor options • Radiometric signal processing compensates for changes in optical properties of the emitters and detectors due to ageing and surface coating • Hygienic sensors have industry standard 3" Triclamp/ Triclover connections Quadbeam sensors incorporate engineering improvements to eliminate water ingress and also withstand the rapid temperature cycling (from 10°C to 80°C) which occurs during CIP cleaning cycles. By design, Quadbeam sensors automatically compensate for component ageing, sensor fouling and daylight interference. The Quadbeam™ alternating light principle is based on a fundamental method of suspended solids measurement by shining a light of known intensity a fixed distance through a medium at a photocell detector. Suspended solids in the medium attenuate some of the light. The detector current gives a measure of the attenuation that corresponds to suspended solids and turbidity measurement. The Quadbeam alternating light principle compensates for variations in light intensity and detector sensitivity by using two detectors and two light sources switched on and off alternatively. The sensors are available with different sensitivity levels and measuring ranges by changing the distances between the light sources and detectors. Sensors with shorter path lengths can measure higher concentrations and have larger measuring ranges where as sensors with longer path lengths are more sensitive to small changes in suspended solids concentration.
