New range of sensors
Carlo Gavazzi has introduced a range of sensors to measure environmental variables including CO2 levels, humidity, temperature and airflow. The new CGES sensors complement the company’s existing offerings to provide complete solutions for energy management, HVAC and smart building applications.
When carbon dioxide levels rise to an unacceptable level it creates poor air quality and stuffy rooms. CO2 and airflow sensors can control extra ventilation to increase the fresh air supply and improve the indoor air quality. Similarly these new devices can be used to control humidity level in wet climates – improving comfort and discouraging the growth of mildew.
Standards introduced by the American Society of Heating, Refrigerating and Air-Conditioning Engineers define a maximum CO2 level of 1000ppm; and the ASHRAE 62-1989 norm has been widely adopted in countries including Sweden, France and Japan as well as the USA.
CGESCO2 sensors use non-dispersive infrared (NDIR) technology to provide measurement ranges 0-2000 or 0-5000ppm. Using a patented auto-calibration procedure to compensate for drift caused by ageing, the sensors ensure traceable high accuracy and outstanding long-term stability. Operation in a closed-loop airstream avoids pollution of the CO2 sensor.
