Dwyer CDD型二氧化碳濃度變送器適用于樓宇自控系統(tǒng)
NDIR技術, 0-2000PPM范圍, 0-10VDC輸出
產品參數(shù)
The Model CDD Duct Mount Carbon Dioxide Transmitter monitors the occupancy in a room by detecting the concentration of carbon dioxide in the return air duct. The non-dispersive infrared sensing technology automatically updates the calibration of the transmitter using a proprietary logic feature which limits the amount of error due to drift. The Model CDD can measure up to 2000 PPM in duct air flows less than 1500 FPM.
