The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.
Jun 23, 2021· Oxygen analyzers measure oxygen levels that are produced from oxygen generators, oxygen concentrators, oxygen systems and oxygen machines. Typically, oxygen analyzers combine oxygen purity concentration (O2), flow (F) and pressure (P). Oxygen analyzers are made up of an oxygen ultrasonic sensor that detects oxygen and nitrogen. Oxygen analyzers range from $300 to $5,000.
Lower Control Limit: The proportional control strategy would position the damper in the minimum position until indoor levels exceed a certain CO2 threshold above outside levels. Typically this threshold should be set at 150 to 200 ppm CO2 above outside levels of at 550 to 600 ppm.
