New Optical CO2 Sensor Using ATR Technology from Anton Paar

Share Article

Carbo 520 Optical is a new process CO2 sensor for beverages that is easily installed directly inline, providing linear, drift-free CO2 readings over the entire measurement range. The basis of this breakthrough: A cutting-edge optical measuring principle called ATR.

Carbo 520 Optical Smart Sensor

Carbo 520 Optical from Anton Paar is an inline CO2 sensor that is easily installed directly inline and in constant contact with the processed sample. Carbo 520 Optical measures CO2 concentration based on the spectroscopic approach of Attenuated Total Reflection (ATR), so the only “motion” in the system is the passing of infrared light through a crystal. Since the sensor has no moving or mechanical parts, there is no wear and tear and no disposables are required. Benefits of the Carbo 520 Optical include:

Minimize your operating costs

  •     Requires 10 W or less
  •     Needs no external purging gas or compressed air
  •     No consumables required

Selective and reliable

  •     Selective CO2 measurement
  •     Not influenced by other gases (such as nitrogen, oxygen)
  •     Color and turbidity are irrelevant to the measurement results

Measure all beverages with a single setup

  •     Sugar composition or solubility have no influence
  •     Same measurement method for all kinds of beverages like colas, beers, wines etc.

Fast results anytime anywhere

  •     Every four seconds
  •     Full connectivity by fieldbus communication (PROFIBUS, ModBus TCP, PROFINET, EtherNet/IP)
  •     Classic analog outputs (4-20 mA) and digital-IOs available

Carbo 520 Optical from Anton Paar is a truly “fit-and-forget” system that provides linear, drift-free CO2 readings over the entire measurement range from 0 g/L to 12 g/L– and gives way to a new kind of certainty in CO2 monitoring throughout the beverage production process.
