Honeywell Carbon Dioxide Sensors and Controllers

Honeywell Carbon Dioxide Sensors

Honeywell's C7632 Carbon Dioxide (CO2) Sensors offer a fixed 0-2000 ppm and fixed 0-10 Vdc output. No adjustments are necessary. The C7632 measures the CO2 concentration in the ventilated space or duct. It is used in ventilation and air conditioning systems to control the amount of fresh outdoor air supplied to maintain acceptable levels of CO2 in the space.

Features:

  • Non-dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas
  • Gold-plated sensor provides long-term calibration stability
  • Fixed 0-2000 ppm, fixed 0-10 Vdc output
  • Used for CO2 based ventilation control [Demand Control Ventilation (DCV)]
  • Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance

Honeywell Carbon Dioxide Sensors/Controllers

Honeywell's C7232 Sensor and Controller is a stand-alone Carbon Dioxide (CO2) Sensor used in determining ventilation necessity with HVAC controllers. The C7232 measures the CO2 concentration in the ventilated space or duct. It is used in ventilation and air conditioning systems to control the amount of fresh outdoor air supplied to maintain acceptable levels of CO2 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
  • SPST relay output
  • Used for CO2 based ventilation control [Demand Control Ventilation (DCV)]
  • Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance
