CDTV-2D404

CDTV-2D404 is a CDTV series carbon dioxide/volatile organic compound transmitter which reducesenergy cost in buildings by lowering the amount of conditioned air based on the occupancy of the space. By sensing both CO2 and VOC, the transmitter can detect fumes that may need to be exhausted during lower occupancy periods. It features single beam dual wavelength NDIR CO2 sensor allows for use in spaces that may be occupied 24 hours a day. Application includes HVAC applications in hospitals, schools, and commercial buildings, demand control ventilation, odour control, waiting rooms or other spaces that may be occupied 24 hours a day.

• Combination VOC and CO2 outputs reduce labor and material costs
• VOC output is correlated to be equivalent to CO2 measurements
• Ventilate using ASHRAE’s occupancy-based VRP Algorithm
• 0 to 2000 PPM CO2 range, duct configuration
• Temperature dependence is ±8 PPM /°C at 1100 PPM
• 4-20mA / 0 to (5 or 10)VDC VOC output
• Duct air velocity range from 0 to 4000FPM (20.32m/s)
• NEMA 4X (IP66) enclosure rating
• Temperature limit ranges from 0 to 50°C
