Carbon Dioxide Sensors

C7232 Carbon Dioxide (CO2) Sensor

• Stand-alone Carbon Dioxide (CO2) sensors and controllers are
  used for determining ventilation necessity with HVAC controllers
  and to manage the amount of fresh outdoor air supplied to
  maintain acceptable levels of CO2 in the space
• 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
• Provides voltage or current output based on CO2 levels
• 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
• CO2 Range: 0 to 2,000 ppm, adjustable
• Analog current output: 0/2 to 10VDC or 0/4 - 20mA selectable
• Response time: 1 minute
• 24VAC/DC, 50/60Hz
