The electrochemical system in the MSA XCell O₂ Sensor uses a non-consuming chemical reaction. O₂ molecules entering the sensor react with the working electrode creating electron flow and water as a byproduct. At the counter electrode, water is converted back into O₂ molecules. The chemical reaction requires a low voltage, which is controlled by the application-specific integrated circuit (ASIC) in the XCell Sensor. Because nothing is consumed or “used up” as the sensor is functioning, the sensor has a longer lifespan. XCell O₂ Sensors have a typical life of more than four years. This non-consuming chemical reaction also means that the sensor can have a much longer shelf-life. The chemical reaction in a traditional lead-based O₂ sensor starts the second the sensor is manufactured. At this time, the chemical process whereby the lead is converted to lead oxide begins and the finite sensor life begins. The MSA XCell O₂ sensor is designed to have a very long shelf-life. While the sensor sits un-powered, no chemical reactions with O₂ are taking place and no life is being depleted from the sen
