Note that each sensor type has a different peak sensitivity to particle size in identical situations. The
Opacity sensor has a peak in the 0.8 micron diameter range (800nm) and Scattering sensor peaks in the
3.5 micron diameter range. The parSYNC® can perceive changes in the distribution of the size of the
particles by using this physical property. These results have been quantified in the literature and in
measured laboratory test.
Evaluating the response of the parSYNC® sensors in a laboratory FTP-75 dynamometer test cycle yields
measured response characteristics that closely follows the theoretical responsivity. For example, a
specific test of a light-duty diesel vehicle (with DPF) yields data below utilizing a TSI EEPS-3090 as a
laboratory spectrometer reference was completed. When characterizing the measured voltage
response of the sensors to the ultra-fine particles, an illustrated log-linear graph below was determined
from laboratory data measuring up to 520 nm diameter.
