Carbon Dioxide (CO2) Sensors
C7232 Carbon Dioxide (CO2) Sensors
The Carbon Dioxide (CO2) Sensors and Controllers are stand-alone
carbon dioxide (CO2) sensors for use in determining ventilation
necessity with HVAC controllers. The sensor measures the CO2
concentration in the ventilated space or duct. The sensors are
used in ventilation and air conditioning systems to control the
amount of fresh outdoor air supplied to maintain acceptable levels
of CO2 in the space.
• Models available with LCD that provides sensor readings
and status information
• Non-Dispersion-Infrared (NDIR) technology used to
measure carbon dioxide gas
• Gold-plated sensor provides long-term calibration stability
• C7232 provides voltage or current output based on CO2 levels
• SPST relay output
• Used for CO2 based ventilation control (Demand Control Ventilation (DCV))
• Automatic Background Cal bration (ABC) algorithm based on long-term
evaluation reduces required typical zero-drift check maintenance
