Room humidity, temperature, air quality and CO2 sensor
室内湿度/温度/空气质量和CO2传感器
AERASGARD® RFTM-LQ-CO2-W
免维护微处理器控制室内传感器AER ASGARD® RFTM-LQ-CO2-W具有自动，手动校准用于检测整个室内气候。它测量的CO2范围为0 ... 2000 ppm或0 ... 5000 ppm，空气质量（VOC）为三种灵敏度级别之一，可选择LOW / MEDIUM（默认）/ HIGH，温度范围为0 ... + 50°C以及相对环境湿度0 ... 100％rH测量值转换为0 -10 V oder 4 ... 20 mA的标准信号（可通过DIP开关选择）。作为选项，可以在照明显示中连续显示测量值。
优雅的塑料外壳，带卡扣式盖子，底座带4孔附件，可安装在垂直或水平安装的墙内冲洗盒上，预先设置断点，用于墙上电缆入口。水蒸气分压的相对湿度（％rH）商除以相应气体温度下的饱和蒸汽压。数字，长期稳定的传感器用作相对空气湿度和温度的测量元件，可确保精确的测量结果。空气质量基于（VOC）气体混合物传感器确定。使用光学NDIR传感器（非色散红外技术）测量空气中的CO 2含量。对于
CO 2 ：0 ... 2000ppm / 5000ppm 可切换， VOC ：0 ... 100％
温度：0°C ... + 50°C， 湿度：0 ... 100％rH
输出：0-10V / 4。 ..20mA 可切换， 带转换触点
The maintenance-free microprocessor-controlled room sensor AERASGARD® RFTM-LQ-CO2-W with automatic and manual calibration is used for detecting the overall room climate. It measures CO2 within a range of 0...2000 ppm or 0...5000 ppm, air quality (VOC) in one of three sensitivity levels that can be selected LOW / MEDIUM (default) / HIGH, temperature within a range of 0...+50°C as well as relative ambient humidity of 0...100 % r.H. The measured values are converted into standard signals of 0 -10 V oder 4...20 mA ( selectable via DIP switches). As an option, the measured values can be shown continuously in the illuminated display.
Elegant enclosure made of plastic, with snap-on lid, base with 4-hole attachment, for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry. The relative humidity (% r.H.) quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. A digital, long-term stable sensor used as measuring element for relative air humidity and temperature guarantees exact measurement results. The air quality is determined based on a (VOC) gas mixture sensor. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). For
CO2: 0...2000ppm / 5000ppm switchable, VOC: 0...100%
Temperature: 0°C...+50°C, Humidity: 0...100% r.H.
Output: 0-10V / 4...20mA switchable, with Changeover contact
