Wi.Tec-Sensorik · The Gas Measurement Company
The O₂.sens from Wi.Tec is based on an electrochemical process. In this process, a chemical reaction takes place with the oxygen to be measured and a liquid electrolyte. During this reaction, 4 electrons are released per oxygen molecule. The resulting sensor current IM or the measuring voltage UM increases proportionally with the number of reacting O₂ molecules. This results in a sensor characteristic curve that increases linearly with increasing O₂ concentration.
