Sensor and Controller

CARBON DIOXIDE SENSOR

APPLICATION

The C7632 Sensor and Controller is a stand-alone carbon 

dioxide (CO

2

) sensor for use in determining ventilation 

necessity with heating ventilation and air conditioning 

(HVAC) controllers. The C7632 measures the CO

2

 

concentration in the ventilated space or duct. The C7632 is 

used in HVAC systems to control the amount of fresh 

outdoor air supplied to maintain acceptable levels of CO

2

 in 

the space.

FEATURES

• Non-Dispersion-Infrared (NDIR) technology used to 

measure carbon dioxide gas.

• Special plated sensor provides long-term calibration 

stability.

• Device provides voltage output based on CO

2

 levels.

• Used for CO

2

 based ventilation control.

• Automatic Background Calibration (ABC) algorithm 

based on long-term evaluation reduces required 

typical zero-drift check maintenance.

• Fixed 0 to 10 Vdc from 0 to 2000 ppm. No 

adjustments are necessary.

• Compatible with Honeywell Excel 10, 15, 5000, and 

any controller requiring 0-10 Vdc input.

Carbon Dioxide Sensor:

Operation: Non-dispersive infrared (NDIR).

Sampling: Diffusion.

Range: 0 to 2000 ppm (fixed).

Annual Drift: ±10 ppm (nominal).

Accuracy: ±(30 ppm+2%) at normal temperature/pres-

sure.

Calibrated at the factory.

Uses automatic background calibration. No calibration 

required for the life of the product.

Meets CEC Title 24 requirement of ±75ppm accuracy at 

600ppm and 1000ppm ambient levels.

For proper CO2 operation, install only in spaces that see 

at least 4 hours of continuous unoccupied time per 

week.
