How does an NDIR CO2 Sensor Work? |

This low power consumption makes the new generation of NDIR CO2 sensors capable of running for months on battery or solar power alone. How NDIR CO2 sensors are made. The fabrication of CO2 sensors resembles that of smartphones or any other state-of-the-art electronics. High-speed robotic assembly takes place in specially designed clean rooms. The modules are then batch-tested and calibrated before shipment. SenseAir AB has a promotional video where you can see sensors …

· I would also like to know what the general life expectancy of a CO2 sensors are? Which brands provide longer life expectancies? How long before most CO2 sensors need to be calibrated? Which brands seem to need less calibration over time? 90% of our CO2 sensors are duct mount. The signal can be either 4 to 20 mA or 0 to 10 VDC and an accuracy of +/- 100 PPM will do. Thanks 02-19 …

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

Similarly, an NDIR sensor works via spectroscopy in that an IR lamp emits a beam of IR light containing a wide energy spectrum (~900nm-100,000 nm) which is measured by the IR detector at the other end of a chamber. When a sample of gas is pumped into the Gas Sample Chamber, certain gases such as CO˚, act as a ˛lter absorbing a speci˛c wavelength of energy within the IR spectrum. Other gases ...
