Description of particle monitoring module principle
Compared with traditional screening and settling methods, the
method of measuring dust concentration by light scattering
principle has many advantages, such as wide applicability, fast
measurement speed, high accuracy and on-line real-time measurement.
The particulate matter in situ measurement module adopts
high-sensitive light scattering photometer (turbidimeter)
technology to measure the particulate matter concentration.The
particulate matter is cutting through a particle cutter firstly to
cut PM2.5 or PM10 particles that we need to measure. After cutting,
the particulate matter goes through the injection port and enters
the optical measurement room. The source generates 880nm of
infrared light to scatter on the particles, and the detector
located at a 90° Angle captures the scattered light. Through the
relationship between the scattered light intensity and the
calibrated particle mass concentration, the mass concentration is
calculated and transmitted to the data acquisition and processing
subsystem in real time.
