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 CO2 based ventilation control. |
|
|
|
|
|
|
|
• 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 CO2 levels. |

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. |
