Combined sensor for measuring carbon dioxide (CO₂), relative humidity and temperature. Especially suitable for applications in air conditioning, for optimum ventilation of apartments, office buildings, event rooms and in gastronomy.
The sensor has a connection housing which contains the evaluation electronics. A proportional 0 – 10 V signal is output over the respective measuring range depending on the measuring variable. This can be combined with ZIEHL-ABEGG control units. There are three 0 – 10 V outputs in total. A display is integrated for showing the measured values which are displayed on this alternately.
