Pressure Sensors in CO2 (R744) HVAC/R Applications

PRESSURE SENSORS IN CO 2 (R744) HVAC/R APPLICATIONS Background Heating, ventilation, air conditioning and refrigeration (HVAC/R) systems use refrigerants to capture heat and then release it to another location by using phase changes, in which the refrigerant transitions from fluid to gas and vice versa. The ideal refrigerant would have acceptable thermodynamic properties, be low in toxicity ...

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0 ...

Carbon dioxide sensors use either infrared light or a chemical process to measure levels of CO2. Sensors are also used to detect volatile organic compounds (VOCs). VOC sensors use a process called photoionization. Ionization is the changing of an atom’s charge. VOC sensors can ionize particles with ultraviolet light and measure electron levels. These measures allow them to detect toxic or ...

CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...
