Telaire Carbon Dioxide Sensors


The Telaire/Amphenol Advanced Sensors Models T5100 and T8041 Carbon Dioxide sensors are designed to monitor the CO2 levels to provide an indication of occupancy for use in demand-controlled ventilation according to ASHRAE Standard 62. Model T5100 wall-mount carbon dioxide sensors are designed to monitor the CO2 concentration in a room. The Model T8041 is a duct-mount sensors with 4" probes that monitor the carbon dioxide levels inside a duct air stream. Each model outputs a 0-10 VDC signal representing a 0-2000 ppm concentration of CO2. Kele is the leading supplier of building automation products.
