CARBON DIOXIDE SENSOR
C7632B
APPLICATION
The C7632 Sensor and Controller is a stand-alone carbon
dioxide (CO
) sensor for use in determining ventilation
2
necessity with heating ventilation and air conditioning
(HVAC) controllers. The C7632 measures the CO
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
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
• Used for CO
based ventilation control.
2
• 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.
