In-line carbon dioxide (CO2) gas transmitter
E E ELEKTRONIK
The elegant, compact housing enables easy installation directly at the ventilation duct using a mounting flange. The EE85 C02 transmitter is also available with an integrated passive temperature measurement.
The CO2 transmitter operates according to the infrared principle (NDIR). The patented auto-calibrate function compensates for any ageing effects (even if there is no fresh air supply) and ensures excellent long-term stability.
The tried-and-tested CO2 sensors from E+E Elektronik ensure high reliability and excellent measurement accuracy. The air to be monitored is conveyed to the CO2 sensor by means of convection via the measuring head and a 12-mm pipe.
Gas exchange with the CO2 sensor is carried out by diffusion via a diaphragm, i.e. the air in the CO2 sensor circulates in a closed system and there is no soiling of the optical measurement path in the CO2 sensor.
The measuring ranges 0...2000 / 5000 / 10000ppm are mapped to the 0...5 V / 10 V or 4...20 mA analog output. A version with switch output is also available as an option.
