GAS | PARTICULATE MATTER Particulate Matter “Particulate matter” (PM) is the general term used to describe solid particles and liquid droplets found in the air. The PM series of transmitters are designed to measure Particulates that include smoke, smog, bacteria, ¬fine dust, liquid droplets, and report the total particle concentration of the monitored environment. ACI’s PM series transmitters utilize a laser particulate matter sensor, that is offered in two different measuring ranges. The PM series transmitters operate on a laser scattering principle, utilizing a fan sampling method. The PM2.5 is designed to detect Particles less than 2.5 μm in diameter. The PM10 is designed to detect Particles less than 10 μm in diameter. The sensor has good long-term stability with an accuracy 10% reading or 10 μg/m3. The room unit features field selectable outputs, 4-20 mA, 0-10 VDC, and Modbus RTU (RS485), relay, and display. The sensor has two jumper selectable working modes for monitoring PM. The Normal Mode monitors the environment continuously and Auto Mode reduces the measuring time to extend service life. The sensor is sent default in Auto Mode. Applications: Monitoring air quality, Air purifiers, WELL Building Standard The PM Series is covered by ACI’s Two (2) Year Limited Warranty. The warranty can be found in the front of ACI’s Sensors & Transmitters catalog, as well as on ACI’s web site, workaci.com.
