Self-calibrating processor-controlled VOC sensor provides air quality measurement. The device is used for quantitative assessment of indoor air saturation with contaminants (e.g. cigarette smoke, expired air, and solvent and detergent vapours). Enables setting the sensitivity level relative to an expected maximum air pollution level. Enables on-demand ventilation which results in considerable energy savings as air is exchanged only upon reaching the pre-set level of air pollution.
DPWQ30600 VOC sensor has 2 analogue outputs: 0–10 V and 4–20 mA. An analogue output provides for stepless fan speed control (requires an EC motor fan or a frequency drive). With stepless control the fan speed is changed in proportion to air quality changes.
The sensor is mounted onto a wall or a mounting box inside the serviced space. The unit is powered from a 24 VAC/VDC low-current electric mains.
