奥地利E+E EE80系列 暖通空调用CO2、相对湿度和温度变送器及开关

        EE80系列建立了暖通空调领域CO2测量的新标准。CO2，相对湿度和温度测量的开关包含在同一个模块中。
        EE80的基础型号 - CO2和温度测量一体式 - 通过安装一个插拔式湿度测量模块，就可便捷的实现功能扩展。
        CO2的测量采用红外线工作原理，其的自动校准程序可对红外源老化进行补偿，从而保证了其的长期稳定性。
        EE80提供模拟信号输出。利用显示器（选项）可以即时显示实际测量的数据。
        另外增加了一个可调节开关点和开关滞后的开关输出选项。
        多种模块形式针对客户的需要提供了解决方案。
