SDS029 Multi-channel Particle Spectrum Sensor

Short Description:

SDS029 is a multi-channel particle spectrum sensor based on the principle of single particle light scattering, which has the functions of particle counter and mass concentration detection. It supports up to 31 particle size channels and can monitor the particle mass concentration and particle size distribution in real time. The product has higher measurement accuracy and particle size resolution, and and has a stronger ability to resist the influence of humidity.

Working Principle

Using the principle of single particle laser scattering, through precise optical design and a gas path designed based on the principles of fluid mechanics, particles in the sampled air can pass through the beam in turn with a high probability, generating weak scattered light; Scattered light is collected through an accurate optical signal collection device and projected onto a highly sensitive, high-bandwidth photodetector.

By identifying and analyzing the scattered pulses of each particle, the corresponding signal strength of each particle is obtained; Obtain the particle size of each particle through a calibration procedure; Converted and aerodynamic School standards, get the mass concentration.
