Honeywell C7632B1002/U Duct Mount CO2 Sensor 0-2000 Ppm

Product Description

The HONEYWELL C7632B1002/U is a duct-mount carbon dioxide sensor designed for continuous CO2 monitoring in mechanical ventilation systems. It outputs a fixed 0-10 Vdc signal that scales linearly across a measurement range of 0 to 2,000 ppm, making it straightforward to wire into building automation systems and DDC controllers. The unit ships without a local display, keeping the form factor compact and suited for in-duct installation where a field-readable readout is not required. Licensed HVAC technicians and building automation contractors are the primary installers of this device.

This sensor is used in demand-controlled ventilation applications across a wide range of environments including indoor air quality monitoring, greenhouse and agricultural facilities, laboratories, food and beverage processing spaces, and parking garages. It installs into a duct section to sample air passing through the system, allowing a BAS or standalone controller to modulate outdoor air dampers in response to occupancy-driven CO2 levels. Its broad application range makes it a common specification in both commercial and industrial mechanical projects.

Key Features

• Measurement range of 0 to 2,000 ppm covers typical IAQ and demand-controlled ventilation thresholds
• Fixed 0-10 Vdc analog output integrates directly with standard BAS and DDC analog input cards
• No display configuration reduces enclosure size and lowers cost where local readout is unnecessary
• Suitable for greenhouse, laboratory, food and beverage, parking garage, and agricultural environments
• Duct-mount form factor samples air in the airstream for representative CO2 readings

Compatibility

Designed as an OEM-style duct-mount CO2 sensor for use with building automation systems and DDC controllers that accept a 0-10 Vdc analog input signal in demand-controlled ventilation applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or building automation controls contractor familiar with low-voltage sensor wiring and duct penetration practices. Power down the air handling unit and de-energize the control panel before making any wiring connections. The sensor probe must be inserted into the duct according to the manufacturer's dimensional guidelines to ensure proper airstream sampling. Follow applicable mechanical and electrical codes, including NEC requirements for low-voltage control wiring, during installation.
