CO2 Sensor for Duct Mounting
EE85
Duct mounted carbon dioxide transmitters of EE85 series are designed for HVAC applications. The CO2 sensing element uses the Non-Dispersive Infrared Technology (NDIR). A patented auto-calibration procedure compen- sates for drift caused by the aging of the sensing element and guarantees outstanding long term stability.
Installed into a duct a small flow of air will be established by convection through the probe into the transmitter housing and back into the duct. Inside the transmitter housing the air will diffuse through a membrane into the CO2 sensing element.
The operation in closed loop air stream avoids pollution of the CO2 sensor.
