Maintenance-free air-quality sensor
AERASGARD
®
FSLQ
with active output, automatic calibration, in the in-wall housing, for determining the air
quality (0…100 % VOC). The measuring transducer converts the measured variables into a standard signal of 0 -10 V. The in-wall sensor is mounted
in high-quality panel switch programmes, ideally of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-wall adapters) either
individually or in combination with light switches, socket outlets, etc.
The sensor is used in offices, hotels, convention centres, apartments, shops, etc. and is used for evaluating the indoor climate.
This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being.
The air quality is detected by a
VOC sensor
(mixed gas sensor for volatile organic substances). This determines the pollutant loading of the room
air by contaminated gases such as cigarette smoke, body vapours, breathing air, solvent vapours, emissions, etc.
