Introduction to the OXY_SMART measurement system

Principle of Operation of the weld gas analyzer

The unit contains a small pump which draws a continuous sample from the purge gas in the welding zone. This sample is passed into a special zirconium detector that is very sensitive to the presence of oxygen. A zirconia sensor is an electrochemical oxygen concentration cell with a solid ceramic electrolyte. It has the property of producing a small emf (voltage) in the presence of oxygen. The relationship between the emf produced by the detector and the oxygen concentration is well understood and highly repeatable. This means that the detector can be calibrated directly in oxygen concentration units. Sensors of this type can be used to measure concentrations from a few ppm all the way up to 100% oxygen. They are very reliable, the calibration is stable over long periods (years) and a detector calibrated for use with low ppm concentration as in the welding application will not saturate or show any degradation when exposed to high oxygen concentrations (air for example).
