Product overview
LD*9 is a high-precision particle sensor based on
the theory of laser MIE scattering. It can continuously collect and
calculate the number of suspended particles with different particle
sizes in air per unit volume, that is the concentration
distribution of particles, and then convert to mass concentration.
And output in the form of universal digital interface.
The sensor can be embedded with various instruments related to the
concentration of suspended particulates in the air or environmental
improvement equipments to provide timely and accurate concentration
data.
Working principle
laser sensor LD*9 adopts MIE spherical particle scattering
principle, that is, laser sensor uses laser to irradiate suspended
particulate matter in the air to produce light scattering,
photoelectric detector collects scattering light intensity in a
certain angle range, the scattering light intensity will be
linearly converted to voltage, and then sent to data processing
system, the data processing system take the principle of Michaelis
scattering theory to deal with the datas, then the equivalent
particle size and the number of particles with different particle
sizes per unit volume are obtained.
