The L-com SRAQ-D661 dust and particulate sensor module is specifically developed for the HVAC industry. This sensor module is used to detect particles as small as 0.03 um, such as cigarette smoke, dust, pollen, and mold spores by using infrared technology. Our sensor module is well suited for building and facilities management, manufacturing environments, and general monitoring of indoor/outdoor air quality applications.

This DIN-rail mounted device requires a 24 VDC power supply and < 50 mA working current. The dust and particulate sensor module available with digital display which shows the particle concentration in real-time. Our 24 V sensor module operates at temperatures ranging from 0 to 65 degrees C and non-condensing 0 to 95% RH humidity.

The SRAQ-D661 module has relay output mode which is activated when the concentration exceeds the adjustable threshold level. This relay output sensor module provides powering to exhaust equipment until concentrations levels are reduced back down to acceptable levels.
