DESCRIPTION
Wall and duct mounted transmitters provide a voltage (0-(5)10 V) or
current (4-20 mA) signal, representing 0-2,000 or 0-5,000 ppm Carbon
Dioxide (CO 2 ) concentration.
Infrared sensing technology provides high accuracy and outstanding
long-term stability.
APPLICATION
To economically sense the concentration of Carbon Dioxide (CO 2 ) in air
for a wide variety of commercial applications, such as demand-controlled
ventilation in buildings, schools, theaters, etc., and transmit to any
compatible electronic analog controller, DDC/PLC control or automation
system in accordance with ASHRAE standards.
