T5000 Series
Telaire® Airestat™ CO2/
Temperature Transmitter
GE Measurement & Control Solutions oers high-
volume manufacturing capabilities for its Telaire
products, a global sales force, and additional
engineering resources to support your sensing
application needs.
Telaire® Technology
The technology is based on the absorption of
light in a gold-plated, reective light pipe or
waveguide diusion gas chamber. A gas permeable
polytetrauoroethylene (PTFE) lter 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.
ABC Logic™ (Automatic Background Calibration)
The Telaire product line oers patented ABC Logic-
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.
Features:
• Low-cost
• Reliable (15 years of low-cost infrared sensor
manufacturing)
• Lifetime calibration guarantee (ABC Logic™ on)
• Pre-calibrated
• Maintenance free (calibration maintained with
patented ABC Logic)
• Flexible congurations (see matrix, page 2)
• Intuitive VLI display
• Three available outputs: analog 0 to 10V, 0 to 5V,
passive temperature (20K thermistor), and digital
UIP interface (RS-232 TTL level)
• User-denable thresholds
• RoHS and WEEE compliant

The Product
The Telaire T5000 Series Airestat CO2 and temperature
transmitter is a low-cost wall-mounted sensing solution
for demand-controlled ventilation. The Airestat provides
an intuitive VLI (Visual Limit Indicator) display for
CO2 thresholds, a passive temperature output (20kΩ
thermistor), and a standard analog 0 to 10 volt or 0 to 5
volt signal to maintain air quality in enclosed spaces (such
as school classrooms, oces, gymnasiums and theaters.)

Please note that the models above are 0-10V output. For
0-5V output, the part number requires -5V (i.e., T5005-5V).
VLI (Visual Limit Indicator)
GE—Telaire Products introduces an exciting new
alternative to traditional scientic LCD display of the CO2
value. Our new T5000 Series transmitter with VLI (Visual
Level Indicator) communicates intuitively to the average
end-user. The correlation between a CO2 PPM reading and
adequate ventilation may not be fully understood. Instead
of oering the user a reading in ppm (parts per million),
we provide a simple LED that communicates increased
CO2 concentrations based on denable or predetermined
thresholds. The LED smoothly transitions between green,
yellow and red as the CO2 threshold is exceeded. Unlike
scientic displays, training to understand ppm values is
not a prerequisite with this innovative product.

* Note: Automatic Background Calibration, or ABC Logic,
is a patented self-calibration technique designed to be
utilized in applications where concentrations will drop
to outside ambient conditions (approximately 400 ppm)
at least four times in a 14-day period, typically during
unoccupied periods.
Full accuracy is achieved after two weeks of operation.
