Energy efficiency and air quality are closely related to each other, because in order to ensure the best possible air quality, it is necessary to consume a significant amount of energy resources, but at the same time, using appropriate equipment, it is also possible to prevent unnecessary energy consumption. This applies especially to particularly demanding applications, where the fulfillment of other requirements must also be ensured.
E+E Elektronik sensors are characterized by high quality, long-term stability and mechanical strength. Sensors of this class are chosen by Professionals who value sensor reliability, measurement accuracy and longevity in the most difficult working conditions.
The E+E EE8915 sensor measures CO2 concentration in the harshest and most demanding conditions. Active pressure and temperature compensation ensures the most accurate CO2 measurement accuracy regardless of ambient temperature, pressure or weather conditions.
EE8915 built-in Dual-Wavelength NDIR CO2 developed by E+E, which:
The multi-point CO2 and temperature adjustment procedure ensures excellent measurement accuracy throughout the temperature operating range. The innovative design allows to combine a short response time and a high protection class. CO2 data is available simultaneously in both voltage and current output signals. The free EE-PCS product configuration software makes it easy to configure and parameterize the EE8915.The EE8915 provides superior performance in any complex process and climate control application.
Carbon dioxide gas (CO2) is a component of the Earth's atmosphere. Although carbon dioxide is invisible and odorless, elevated CO2 content in indoor air causes fatigue and impairs people's ability to concentrate. In rooms with high occupancy, such as conference rooms and theaters, the negative effect on people becomes even more obvious. CO2 is an essential parameter for optimizing indoor air quality and process control. High concentrations of CO2 are used, for example, in agriculture, refrigeration or the beverage industry, where leaks can be dangerous to living beings and require special safety measures.
~ 40,000 ppm - human exhaled breath (20L CO2/h / 0.7ft3/h)
~ 5000 ppm - CO2 concentration limit in the workplace
> 1000 ppm - fatigue and reduced concentration
~ 1000 ppm - recommended max. CO2 levels in indoor air
~ 400ppm - outdoor air
E+E Elektronik CO2 sensors are equipped with a Dual-Wavelength NDIR CO2 element. What does it really mean? One detector is tuned to the 4.2 µm wavelength absorbed by CO2, the other detector is tuned to 3.9 µm unaffected by any gas. The CO2 concentration is calculated for each measurement from the outputs of both detectors. In this way, a high resistance to contamination, wear and tear is achieved, and automatic compensation ensures long-term stability.
