Installation costs save with combined CO2-/Temperaturmessung

For the precise measurement of the CO2-Konzentration and the temperature in HLK applications E+E electronics extended the proven CO2 transducer EE85 with an additional passive temperature measurement. CO2 and temperature measurement in equipment the installation costs of Sensorik.Der lowers combined CO2-/Temperatur transducer is in the best way for applications within the range building management, ventilation and controlled dwelling ventilation suitable. The graceful designed, compact housing permits a simple assembly by means of assembly flange directly to L�ftungskanal.Die the CO2 to measurement of the EE85 works according to the infrared principle (NDIR). The patented autocalibration procedure compensates effects of aging also without admission of fresh air and provides for a outstanding long-term stability. Air which can be supervised is led by convection over the measuring head and a 12mm pipe to the Messzelle in the housing. The gas exchange with the Messzelle is made by a diaphragm via diffusion. Therefore the gas circulates in the Messzelle in a closed system. A dirt load of the optical measuring section and associated inaccuracies thereby are prevented. The temperature sensor is inserted directly in the point of the sensor and by a membrane filter in the best way protected against contamination. The passive temperature sensor signal is available at the connecting terminals in the housing and can be attached to most controls directly. As measuring range stands 0 � 2,000/5,000/10,000 ppm to the selection. The temperature area of application amounts to -20 � 60�C.Da a CO2-Konzentration of the spatial air impaired of more than 1,000 ppm our efficiency, is important it to seize apart from the usual room climate values such as temperature and relative dampness also the CO2-Konzentration. Thus promptly and energy-saving measures can be introduced approximately � bad � air - for example the increase meeting demand of the admission of fresh air. �
