Duct Sensor
The wall and duct-mounted carbon
dioxide (CO
2
) sensors are designed
especially for demand-controlled
ventilation zone applications. The sensor
is compatible with Trane VAV and
VariTrac
®
controllers. Long-term stability
and reliable sensing performance come
from advanced silicon based Non-
Dispersive Infrared (NDIR) technology.
When connected to a building
automation system and the appropriate
ventilation equipment, the Trane CO
2
sensors measure and record carbon
dioxide in parts-per-million (ppm) in
occupied building spaces. These carbon
dioxide measurements are typically
used to identify under-ventilated
building zones and to override outdoor
airflow beyond design ventilation rates
if the CO
2
exceeds acceptable levels.
