Particulate concentration

Optical technology for continuous measurements

The fine dust sensors are optical sensors for continuous measurement and control of fine dust contents, three particulate sizes are available: simultaneous PM10 and PM2.5, and separate PM 2.5 and PM10. The determination of the dust content is based on the method of scattered light measurement. The sucked air is tempered. The flow enforcement takes place via the integrated fan (2 l/min). In the device there is a periodic control and correction of zero point and reference point which is enabled by the electrostatic precipitator with integrated high voltage module. A high zero-point stability is achieved by evaluation of the internal measuring signals.
