Honeywell Duct Miscellaneous

Overview

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…
