CDTA二氧化碳探測器 包括二氧化碳、濕度、溫度和具有覆蓋功能的溫度設置點。 通過現(xiàn)場選擇的Modbus®和BACnet通信，只需要四根電線的電力和通信信號。 所述通信檢測器可以串接在一起，進一步降低了安裝成本。 為了減少設置時間，使用DIP開關設置RS-485 MAC地址。 第二組DIP開關用于選擇輸出是Modbus®RTU還是BACnet MS/TP通信協(xié)議，并限制對set up菜單的訪問。 CDTA系列使用單光束雙波長非色散紅外(NDIR)傳感器來測量二氧化碳水平。 可以現(xiàn)場校準， 氣壓可以根據海拔高度調整。 濕度使用電容式聚合物傳感器，溫度使用10KO熱敏電阻傳感器測量。 濕度傳感器是現(xiàn)場可更換的，不需要額外的校準。 可選的本地和遠程顯示器可用于顯示任何參數, 液晶顯示器可編程顯示溫度、濕度或溫度設定值。
產品應用 需求控制通風，在學校，辦公大樓，醫(yī)院，和其他室內環(huán)境
