What is Particulate Matter? , PM10, Health Effects, …

A particulate matter sensor and a typical air quality monitor have generally the same function, which is to detect the concentration levels of airborne contaminants. Air quality monitors focus on general levels of pollutants, with only specialized ones capable of identifying the type of pollutants present. On the other hand, particulate matter sensors focus on determining the levels of and PM10 present, which …

Particulate Matter Sensors | Honeywell

Particulate matter sensors include the HPM Series, a laser-based sensor that uses the light scattering method to detect and count particles in the concentration range of 0 μg/m 3 to 1,000 μg/m 3 in a given environment. A laser light source illuminates a particle as it is pulled through the detection chamber. As particles pass through the laser beam, the light source becomes obscured and is recorded on the …

Soot (PM) Sensors - DieselNet

Abstract: Various types of soot or particulate matter sensors have been developed to estimate the amount of soot in a diesel particulate filter or to detect excessive PM emissions downstream of a DPF in case of a filter estimation of soot mass in the filter largely relies on a differential pressure measurement, but other methods such as radio frequency (RF) sensors have also been developed.
