AERASGARD® ALQ-CO2 MODBUS

Art.nr. 1501-7111-6071-200
EAN 4 251325 613420

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.
