Digital Optical Suspended Solids Sensor Ip68 IR Absorption

Digital Optical IR Suspended Solid Sensor IP68 Based On IR Absorption

The measuring principle of the digital IR suspended solid sensor is based on the mitigation of the Infra-Red signal in 870 nm through an optical path of 5mm. The sensor delivers measures in Suspended Solid (g/l), Turbidity (FAU) and Sludge Blanket detection in % of transmission IR. For better precision, the optics of the sensor are regulated in temperature.

For a measure of Suspended Solid, the sensor is directly calibrated on the material to be measured (sample of sludge).In the Turbidimeter version, the sensor delivers measures on a range of 0-4000 FAU ( Formazine Attenuation Unit) and is calibrated with solutions of Formazine. Temperature: measures and regulation of optics via CTN.

Application Of The IR Suspended Solid Sensor

• Urban wastewater treatment (Inlet/ sewage water (SS, Turbidity), Aeration basin (SS), Outlet (Turbidity))
• Industrial effluent treatment (Aeration basin (SS)), Clarifier (Sludge blanket), Outlet (Turbidity))
• Sludge treatment (Centrifugation)

• Dredging site (turbidity)
