BioPAT® Xgas 25/75 with DN 40 TC 64

The BioPAT® Xgas combines one oxygen and one carbon dioxide sensor featuring automatic compensation of humidity and pressure into one compact analyser. The gas to be analysed flows through the integrated flow adapter past the measuring chambers. During this process, the pressure, humidity, oxygen and carbon dioxide concentration are measured. The zirconium-dioxide sensor measures the oxygen concentration over a range of 1 to 50% with an accuracy of under 0.2% full scale over the whole measurement range with a ±3% reading on the value. The measurement principle requires the sensor temperature to be 580°C (1,076°F) and operates to specification for up to 15,000 hours (approx. 20 months) with less than 2% drift. The O₂ sensor requires a minimum of 0.1% oxygen during operation to avoid damage to the electrode cell. Therefore, sensor exposure to non-oxygen gas mixtures must be avoided. The dual-wavelength infrared sensor detects the carbon dioxide concentration over a range of 0 to 10% with an accuracy of under 0.2% FS over the whole measurement range with a ±3% reading on the value. The robust sensor operates for up to 20,000 working hours (approx. 25 months) with less than 2% drift. As a non-standard, the sensor can be recalibrated to measure higher concentrations of CO₂ at a lower accuracy.
