Sensor and Controller
CARBON DIOXIDE SENSOR
APPLICATION
The C7232 Sensor and Controller is a stand-alone carbon
dioxide (CO
2
) sensor for use in determining ventilation
necessity with HVAC controllers. The C7232 measures the
CO
2
concentration in the ventilated space or duct. The C7232
is used in ventilation and air conditioning systems to control
the amount of fresh outdoor air supplied to maintain
acceptable levels of CO
2
in the space.
FEATURES
• 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.
• Device provides voltage output based on CO
2
levels.
• Models available with SPST relay output.
• Used for CO
2
based ventilation control.
• Automatic Background Calibration (ABC) algorithm
based on long-term evaluation reduces required
typical zero-drift check maintenance.
