Description

Room CO2 sensor and measuring transducer AERASGARD® RCO2-W
Maintenance-free AERASGARD® RCO2 - SD room air quality measuring transducer with active output, automatic calibration (fixed), in an elegant plastic housing with snap-on cover, for determining the CO2 content of the air (0...2000 ppm). The transmitter converts the measured values into a standard signal of 0-10 V.

Maintenance-free AERASGARD® RCO2 - W room air quality measuring transducer with active/switching output, automatic calibration (can be deactivated), in an elegant plastic housing with snap-on cover, optional with traffic light indicator (five coloured LEDs), for determining the CO2 content of the air (0...2000 ppm/0...5000 ppm). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).

The sensor device 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.
The CO2 content is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as the monitoring of residential and conference rooms.
