CO2 4-20mA Transmitter
SKU: CMS-150
Three wire 4 to 20 mA sensor detects carbon dioxide concentration from 0 to 3000 ppm.
The PHG transmitter measures CO2 concentration in in-door atmospheres and converts it into standard current or voltage signal. PHG model uses dual nondispersive infrared (NDIR) carbon-dioxide sensor providing improved accuracy and sensitivity as well as low temperature and humidity dependence.
The transmitter can be equipped with local 4-digit LED display and RS232 serial interface. PHG mounting variants include free or duct installation with top or bottom mounted connector.
PHG application area includes indoor air control, ventilation, air-conditioning, mushroom control, etc.
- Low Cost
- Dual NDIR sensor built in
- Good accuracy, sensitivity and selectivity
- Low humidity and temperature dependency
- For HVAC and food processing applications
- Comeco Part No: PHG-B.03.X.F
Please note that the datasheet mentions a range of options, not all of which we stock. We may be able to bring in sensors with different options, but minimum orders and different pricing may apply. Contact us for further details.
