Sensors for air quality
Type Item no. ADG Euro / pc.

CO 2 - and temperature transducer see our
Measuring range CO 2 : 0 – 3,000 ppm; temperature 0 – 50 °C current
(factory-made preset to 0 – 2,000 ppm) for regulation of the price list
demands of ventilation systems dependent on number of
people. The measuring principle is based on non-dispersive
infrared technology with automatic self-calibration. 5 year service
intervals. Output for CO 2 and temperature: 0 – 10 V or
4 – 20 mA each, programmable. If equipped with LCD display,
the concentration of CO 2 and the temperature are shown SENSORS
alternately; serial communication interface.
Voltage supply: 24 V AC / DC ± 20 %
Permiss. amb. cond.: 0 – 50 °C, 0 – 95 % RH
(non-condensing)
Housing for vertical interior wall fastening.
Housing: 61 x 97 x 19 mm (L x W x D); white; IP 30
