T8042

GE Measurement & Control Solutions ® Ventostat T8041/T8042 Telaire CO2 Duct Probe Transmitters GE is excited to announce to announce a new generation of Telaire CO2 transmitters targeting indoor air quality and energy conservation applications. The Ventostat® T8041/T8042 duct mount CO2 transmitters offer accuracy and versatility at an affordable price. This exceptional product line touts an unobtrusive form factor that is easy to install, simple to use, and remains accurate over the expected life of the device using Telaire’s patented ABC Logic™ (Automatic Background Calibration) technology. Features • Simple installation (mounting hardware and instructions included) • Gas permeable, water resistant diffusion filter prevents particulate and water contamination of the sensor • Two models with different probe lengths to suit a variety of return air duct sizes • RoHS compliant • Offers standard 0-10 volt or 0-5 volt output • Patented absorption infrared/gas sensing engine provides high accuracy in a compact low-cost package • Patented ABC Logic™ self-calibration system eliminates the need for manual calibration in most applications • Lifetime calibration guarantee (ABC Logic™ on) Applications CO2 transmitters can be used in a broad range of applications including air quality monitoring in buildings. CO2 concentration levels in buildings are monitored to provide an indication of occupancy and to drive a ventilation control strategy. An effective DCV (Demand Controlled Ventilation) strategy will conserve energy and maintain indoor air quality. Installation Instructions 1. Before installing the sensor, note the direction of the airflow. 2. Drill/cut one [38.10 mm] 1 ½” hole. Punch/drill two [3.17 mm] 1/8” holes for mounting screws. 3. Slide sensor into [38.10 mm] 1 ½” hole and secure with screws. 4. Connect the conduit and make necessary wire connections. 5. Install lid, and ensure it snaps into place. 24 AWG 24 VAC Installation Drawing for T8041 and T8042 (T8042 Installation shown) Dimensional Drawings 143.66 5.66 77.46 3.05 31.50 [1.24] 77.46 3.05 103.77 4.09 40.19 1.58 T8041 Dimensions (All Dimensions are in MM [Inch].) 143.66 5.66 77.47 3.05 77.46 3.05 31.50 [1.24] 40.19 1.58 205.08 8.07 T8042 Dimensions (All Dimensions are in MM [Inch].) Model T8041/T8042 Specifications Technology The technology is based on the absorption of light in a gold-plated reflective light pipe or waveguide diffusion gas chamber. A gas permeable PTFE filter prevents particulate and water contamination of the sensor. Light is absorbed in proportion to the CO2 concentration and the remaining light is measured and converted into an analog signal.
