5 HVAC sensors you need to know about Primex HVAC Venting

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 combustible gases. Gateway technology and sensors. Many of your customers legacy HVAC systems have a lot of life left in them. And while they would benefit from sensor technology that goes beyond the basic thermostat, they don’t want to replace a system …

Why measure CO2 in HVAC applications? |

Instead of constantly providing fresh air, buildings used carbon dioxide sensors to “sense” when the buildings were occupied. When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no longer breathing in the room, and the fresh air dampers close.
