The VB5 sensor uses a measuring principle based on the attenuation of the IR signal at 870 nm through a 5mm optical slit. The sensor provides sludge blanket measurements as a % of IR transmission. For better accuracy, the sensor optics are temperature regulated. The DELRIN sensor is particularly well suited to the following application areas: · Urban wastewater treatment: Primary and final decanter. · Treatment of industrial effluents: Primary and final settling tank. · Private sanitation Measurements Measurement principle Sludge Blanket measuring ranges Sludge blanket resolution Sludge blanket accuracy Measurement range (Temperature) Resolution (Temperature) Accuracy (Temperature) Storage temperature Sensors Max.
