Air Quality Transmitter
0 to 10 VDC Output
Humans respirate Volatile Organic Compounds (VOCs) as well as CO2. The BAPI sensor measures these VOCs and indicates when a space is occupied just as well as a CO2 sensor.
The advantage of the VOC sensor is that it measures air contaminants from other sources besides respiration, such as building materials, cleaners, perfumes and furniture and carpet off-gassing. Using this sensor for Demand Controlled Ventilation then is a way of achieving true indoor air quality, rather than just CO2 dilution.
A further benefit is that it requires no additional work on your part. ThatÛªs because the sensor converts the VOC reading to a CO2 equivalent level. This lets you use AshraeÛªs CO2-based VRP schedule to ventilate.
BAPIÛªs VOC Duct Sensor samples duct air using an aspiration tube. Moving air from the duct enters the tube, is forced into the BAPI-Box enclosure and exits through the other half of the tube. As long as there is air movement in the duct, air is continuously exchanged.
