Use of CO2 to control ventilation is one of the fastest growing areas in building control. A primary reason for this growth is that the technology has now matured to the point where it is inexpensive, easy to use and reliable. Amphenol Advanced Sensors leads this trend with a number of unique innovations in its sensor design. This article explains a key patented feature of Amphenol Advanced Sensors’ technology called ABCLogic that enables CO2 sensors to automatically calibrate themselves once installed in the field. This feature eliminates one of the biggest concerns surrounding CO2 sensing… sensor drift and maintenance.

Air Quality Sensors - Particle Matter, CO2, Humidity Temperature and Dust Products - Telaire products have been at the forefront of Carbon Dioxide sensing technology for the last 25 years and are the originators of the maintenance free CO2 Non Dispersive Infrared (NDIR) sensor. Telaire has over 35 patents around its technology, including ABC logic that warrants calibration for the life of the sensor. Telaire OEM components are used extensively in heating and ventilation control and Industrial applications.

And they protect the environment from harmful emissions. Consider us your global partner for all your automotive sensor needs.

Carbon dioxide is one of the most plentiful by products of the combustion process used by automobiles, trucks and fuel-fired appliances. For properly operated and maintained equipment CO2 will be produced in quantities 100 times or greater any other combustion byproduct considered harmful, including carbon monoxide, hexane, nitric oxide or nitrogen dioxide. This article shows a breakdown of the by-products of combustion by volume (in ppm) for an automobile at idle.

A simple tool made by a Santa Barbara Company for measuring indoor air quality and ventilation in buildings is now being used to quickly identify if shipping containers are carrying a hidden human cargo.

Ventilation is an important part of maintaining a comfortable, healthy, productive environment for students and faculty. Improper ventilation can have a negative impact on occupant health and performance, increase the risk from litigation and/or waste energy. Numerous organizations now require and/or recommend CO2-based ventilation control in different commercial HVAC applications. The following article give examples and links to these codes, standards, and reports. Also, some utility companies offer rebates to building owners for installing CO2 sensors. Other utility may offer rebates based on the energy savings potential, so check with your local power provider.
