Goleta, Calif. – July 25, 2007.

Amphenol Advanced Sensors announces its new generation of Telaire CO2 transmitters, which target indoor air quality and energy conservation applications. The Ventostat® T8031 / T8041 Duct Mount and Airestat® T5000 Series Wall Mount offer accuracy and versatility at an affordable price. The 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 utilizing Telaire’s patented ABC Logic™ (Automatic Background Calibration) technology.

“Amphenol Advanced Sensors' Telaire CO2 Transmitter product line represents a marked improvement in size, ease of use and customer installation,” said Dave Michels, Global Product Manager for Telaire, Amphenol Advanced Sensors. “The Transmitter family was designed using customer input to meet a broad range of application needs.

The new Ventostat® T8031 Duct Mount CO2 Transmitter is one of the smallest in-duct CO2 sensors on the market. Its modest form factor accommodates small diameter (6”) HVAC return air ducts and utilizes the T8041 Duct Mount Probe to measure CO2 concentrations in larger air ducts. Both products offer a standard analog 0 to 10 volt output, mounting hardware and simple mounting instructions.

The Airestat T5000 Series Wall Mount CO2 Transmitter offers user definable thresholds and a visual limit LED indicator (green, yellow and red) for measured CO2 concentrations. The T5000 series also provides a passive temperature and a standard analog 0 to 10 volt output. This device is an essential tool for maintaining an indoor air quality strategy for school classrooms, offices, and many other applications. “We are very proud of HygroTrace’s UL508 certification and its selection for the SemiCon West Technology Innovation Showcase,” said John Kerney, GE Sensing Global Product Manager for Gas & Moisture. “The recognitions demonstrate HygroTrace’s advanced technology and high quality performance.”

The technology is based on the absorption of light in a gold-plated reflective light pipe or waveguide diffusion gas chamber. A gas permeable Teflon 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.

Amphenol Advanced Sensors' ABC Logic™ software ensures a 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.

CO2 transmitters can be utilized 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 Demand Controlled Ventilation (DCV) strategy will conserve energy and maintain indoor air quality.
