SENVA AQ2D-BC2AAKD Total Sense Series Duct Air Quality Sensor
Duct Air Quality Sensor
Build a complete air quality system for indoor, duct, and outdoor Six environmental sensors: PMx, VOC, CO2, RH, T, barometric pressure BACnet/Modbus or analog outputs with set-point relay
DESCRIPTION
The Total Sense Series Duct AQ sensor provides more data for more advanced ventilation control while drastically reducing installation cost and time on a project. It includes a comprehensive selection of AQ sensing with carbon dioxide (CO2), relative humidity (RH), and temperature plus options for total volatile organic compounds (TVOC), barometric pressure and particulate matter (PM).
APPLICATIONS
- Measure duct air quality to validate filtration systems and deliver fresh air

- One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
- Models with PM sensor included achieve ±5% accuracy over 0 to 80%RH range and an additional temperature shift of up +0.5° C
- Time for reaching 63% of reading at 25° C and 1 m/s airflow
- Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours.)
- Product improvement is a continual process at Senva and product features and specification may change without prior notice. Refer to instructions that accompany the product for installation and wiring.
