CDTA二氧化碳探测器 包括二氧化碳、湿度、温度和具有覆盖功能的温度设置点。 通过现场选择的Modbus®和BACnet通信，只需要四根电线的电力和通信信号。 所述通信检测器可以串接在一起，进一步降低了安装成本。 为了减少设置时间，使用DIP开关设置RS-485 MAC地址。 第二组DIP开关用于选择输出是Modbus®RTU还是BACnet MS/TP通信协议，并限制对set up菜单的访问。 CDTA系列使用单光束双波长非色散红外(NDIR)传感器来测量二氧化碳水平。 可以现场校准， 气压可以根据海拔高度调整。 湿度使用电容式聚合物传感器，温度使用10KO热敏电阻传感器测量。 湿度传感器是现场可更换的，不需要额外的校准。 可选的本地和远程显示器可用于显示任何参数, 液晶显示器可编程显示温度、湿度或温度设定值。
