(R) (R) Telaire Duct Mount Sensor Telaire Ventostat(R) T8031 CO2 Duct Mount Transmitter Amphenol Advanced Sensors is excited to announce the release of a new generation of Telaire CO2 transmitters targeting indoor air quality and energy conservation applications. The Ventostat(R) T8031 duct mount CO2 transmitter offers 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 LogicTM (Automatic Background Calibration) technology. Application 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. Features * One of the smallest in-duct CO2 transmitters on the market * Simple installation (mounting hardware and instructions included) * Ideally suited for OEM manufacturers that must accommodate smaller < 6 in (15.2 cm) HVAC return air ducts. * Offers standard 0-10 volt output * Patented absorption infrared/gas sensing engine provides high accuracy in a compact, low-cost package * Patented ABC LogicTM self-calibration system eliminates the need for manual calibration in most applications * Gas permeable, water-resistant diffusion filter prevents particulate and water contamination of the sensor * Lifetime calibration guarantee Amphenol Advanced Sensors Model T8031 Specifications Description (R) Telaire Ventostat T8031 CO2 duct mount transmitter is the smallest package available. T8031 CO2 Sensor Red Wire Input Power 18 VDC to 42 VDC or 18 VAC to 30 VAC RMS 50/60 Hz The T8031 is a CO2 transmitter designed to be installed in HVAC return air ducts. The size of the board and the dimensions of the case have been optimized to place the transmitter in small, i.e. 6 inch [15.24 cm] diameter, return air ducts. This product offers a sleek design, a simple analog output, and it is easy to install. The transmitter includes mounting hardware and installation instructions. Measurement Range 0-2000 ppm factory calibrated Duct Air Velocity 0 to 1500 ft/min (0-450 meter/min) Temp Dependence 0.2% of full scale per C *Accuracy 40 ppm +3% of reading @ 22C (72F) when compared with a factory certified reference Non-linearity <1% of full scale @ 22C (72F) Pressure Dependence 0.13% of reading per mm of mercury Sensor Optics Power Supply Controller Violet Wire Analog Out (0 to 10 VDC) (0 to 2000 PPM) Common Black Wire Operating Conditions * Temperature: 0C to 50C (32F to 122F) * Humidity: 0 to 95% relative humidity, non-condensing Storage Conditions -20C to 70C (-4F to 158F) Certifications RoHS compliance FCC Part 15,B CE EMC EN61000-6-2, class B, criterion B* *Deviations of the output signal may occur during strong electrical fast transients on the power line Enclosure flammability rating - UL94-5VA Output Analog 0 to 10 VDC (100 ohm output impedance) Power Supply Requirements 18 to 30 VAC RMS, 50/60 Hz or 18 to 42 VDC, polarity protected. Power Consumption Typical values (1.65 watts peak, 0.65 watts avg. @ 42 VDC) Sensors will be calibrated at zero and span at the factory. Calibration in the field will not be required. Sensors will be shipped with ABC LogicTM turned on. *Note: The Telaire product line offers patented ABC LogicTM software for self correction of drift to better than 20 ppm per year. The system is virtually free of maintenance and typically has a lifetime of more than 10 years. Response Time Physical Requirements *Calibration Three minutes typical for 90% step change at low duct speeds Warm-up Time < Two minutes (operational); 10 minutes to achieve maximum accuracy Amphenol Advanced Sensors Dimensions: Length: 3.83 in (9.72 cm) + 0.74 in (1.87 cm) mounting tab Width: 1.17in (2.97 cm) Height: 0.94 in (2.38 cm) Color: 701 Black Flammability Classification: UL 94V-5 www.amphenol-sensors.com (c) 2014 Amphenol Corporation.
