Description

AERASGARD®
The maintenance-free on-wall sensor AERASGARD® AFTM - LQ- CO2 - Modbus (max. expansion level) and AFTM - CO2 - Modbus with Modbus connection, automatic calibration, in an impact- resistant plastic housing with quick-locking screws, plastic sinter filter (replaceable), optionally with/without display, for determining the CO2-content of the air (0...5000 ppm), of the air quality (0…100 % VOC), the temperature (–35...+80 °C) and the relative air humidity (0…100 % RH). International system of units SI (default) can be changed to imperial (via Modbus).
The following parameters can be accessed via the Modbus: Temperature, relative humidity, air quality (VOC), carbon dioxide (CO2) and atmospheric pressure. The sensor is used in offices, hotels, convention centres, apartments, shops, etc. for the purpose of evaluating the indoor climate. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. One sensor for every 30 m² of space is recommended.
A long-term stable, digital humidity and temperature sensor guarantees exact measurement results. The CO2 measurement is performed using an optical NDIR sensor (non-dispersive infrared technology). The detection range is calibrated for standard applications such as monitoring residential rooms and conference rooms. The air quality is detected by a VOC sensor (mixed gas sensor for volatile organic substances). This sensor determines the loading of the room air due to contaminated gases such as cigarette smoke, body perspiration, exhaled breathing air, solvent vapours, emissions etc. With regard to the expected air contamination, low, medium or high VOC sensitivity can be selected.

Innovative Modbus sensor with galvanically separated RS485-Modbus-interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated; with customised programming in the 7-segment and dot-matrix range). The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
