Multifunctional on-wall sensors and measuring transducers, for CO2 content and air quality (VOC)

AERASGARD® ALQ-CO2 - Modbus

多功能墙上CO2和空气质量测量传感器

免维护，微处理器控制AERASGARD®AFTM - LQ - CO2 - Modbus和 ACO2 - Modbus / ALQ - CO2 -带Modbus连接的Modbus，带/不带可选显示器，专为墙上安装而设计，用于监控所有与房间内气候相关的被测量值。这些是测量空气湿度，温度，CO2浓度以及空气质量（VOC）。通过使用单个设备监控所有四个被测量，可以有效地监控和调节整个房间气候。它测量的CO2范围为0 ... 5000 ppm，VOC为三种可选灵敏度级别之一LOW / MEDIUM / HIGH，温度范围为-35 ... + 80°C，以及相对空气湿度来自0 ... 100％rH

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。

CO 2：5000 ppm
VOC：0 ... 100％

The maintenance-free, microprocessor-controlled AERASGARD® AFTM - LQ - CO2 - Modbus and ACO2 - Modbus ⁄ ALQ - CO2 - Modbus with Modbus connection, with ⁄ without optional display, is designed for on-wall installation and is used to monitor all measurands of relevance to the climate inside a room. These are the measurands air humidity, temperature, CO2 concentration as well as air quality (VOC). By using a single device to monitor all four measurands, it is possible to effectively monitor and regulate the entire room climate. It measures CO2 in the range of 0...5000 ppm, VOC at one of three selectable sensitivity levels LOW / MEDIUM / HIGH, temperatures in the range of –35...+80 °C, as well as relative air humidity from 0...100 % r.H.

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 measure ments, 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.
