Multifunctional on-wall sensors and measuring transducers, for humidity, temperature and CO2 content
多功能壁上湿度，温度和二氧化碳含量传感器和测量传感器
AERASGARD® AFTM-CO2-W
免维护微处理器控制的上壁传感器AER ASGARD® AFTM-CO2 -含具有自动，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-35 ... + 80°C以及相对环境湿度0 ... 100％rH测量值转换为0 -10 V或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。
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。
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。传感器的检测范围针对标准应用进行校准，例如监控住宅和会议室。根据需要进行房间通风，改善福祉和客户利益，提高舒适度以及通过节能降低运营成本只是使用AERASGARD®CO2传感器的一些好处。
上述解释表明，对于VOC测量，有二氧化碳测量的应用，但从我们的角度来看，两种被测量的组合。在这方面的关键因素是这两种被测量都不能相互转换，并且不能相互推导或相互推导。NDIR CO2测量仪器选择性地测量并且不能检测任何VOC; VOC混合气体传感器无法识别CO2分子。
测量范围湿度：0 ... 100％r。H.
测量范围温度：-35 ... + 80°C

The maintenance-free microprocessor-controlled on-wall sensor AERASGARD® AFTM-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 –35...+80 °C as well as relative ambient humidity of 0...100 % r.H. The measured values are converted into standard signals of 0 -10 V or 4...20 mA (selectable via DIP switches). As an option, the measured values can be shown continuously in the illuminated display. 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 CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the sensors is calibrated for standard applications such as monitoring residential rooms and conference rooms. Room ventilation on an as-needed basis, improved well-being and customer benefit, increased comfort as well as reduced operating costs through energy conservation are just some of the benefits of employing the AERASGARD® CO2 sensor. The explanations above demonstrate that there are applications for CO2 measurements, for VOC measurem ents, but from our perspective, above all, for a combination of both measurands. The crucial factor in this respect is that both of these measurands are not convertible into each other and derivations to or from one another cannot be made. An NDIR CO2 measuring instrument measures selectively and cannot detect any VOC; a VOC mixed gas sensor cannot recognize CO2 molecules.
