2.2.8 MES5 sensor: Sludge Blanket detection, Suspended Solid, Turbidity.
The principle of measure 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 a 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 Turbidimeter version the sensor delivers measures on a range 0-4000 FAU (Formazine Attenuation
Unit) and is calibrated with solutions of Formazine.
Temperature: measures and regulation of optics via CTN.
