Carbon Dioxide (CO2) Sensors

C7262 Carbon Dioxide (CO2)/Temperature Sensors

The C7262 Sensor is a stand-alone carbon dioxide (CO2) and
temperature sensor for use in determining ventilation necessity
with HVAC controllers. The C7262 measures the CO2 concentration
and temperature to control the amount of fresh outdoor air
supplied to maintain acceptable levels of CO2 in the space.

• Used for CO

• Integral 20K ohm NTC temperature output.

• Models available with LCD that provides CO2 ppm level.

• Non-Dispersion-Infrared (NDIR) technology used to measure carbon
dioxide gas.

• Device provides voltage or current output based on CO

• Models available with SPST relay output.

• Automatic Background Cal bration (ABC) algorithm based on long­term evaluation reduces required typical zero-drift check
maintenance.

C7632 Carbon Dioxide (CO2) Sensors

The Carbon Dioxide (CO2) Sensors offer a fixed 0-2000ppm and
fixed 0-10Vdc output. No adjustments are necessary. Like the
C7232 sensors, these are for use in determining ventilation
necessity with HVAC controllers. The sensor measures the CO2
concentration in the ventilated space or duct. The sensors are
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.

• Non-Dispersion-Infrared (NDIR) technology used to
measure carbon dioxide gas

• Gold-plated sensor provides long-term calibration stability

• Fixed 0-2000ppm, fixed 0-10Vdc output

• Used for CO2 based ventilation control (Demand Control Ventilation (DCV))

• Automatic Background Cal bration (ABC) algorithm based on long-term
evaluation reduces required typical zero-drift check maintenance
