Answers

#SensorFAQs – Q16 1/5 | The zirconium dioxide O2 sensor working principle measures partial pressure of oxygen in a mixture of gases. This typically causes confusion amongst SST’s customers as most oxygen sensors on the market measure oxygen concentration. https://t.co/N15okQwn6W

#SensorFAQs – Q16 2/5 | But, what is partial pressure? It is a question we are asked frequently when it comes to the O2 sensor working principle.

We will explain the definition, the physics behind it and also direct you to our website where we show you how to calculate it. https://t.co/N15okQwn6W

#SensorFAQs – Q16 3/5 | Partial Pressure: The Definition

The partial pressure is defined as the pressure of a single gas component in a mixture of gases. It corresponds to the total pressure which the single gas component would exert if it alone occupied the whole volume. https://t.co/N15okQwn6W

#SensorFAQs – Q16 4/5 | Daltons Law: The Physics

The theory of the o2 sensor working principle is detailed here. The total pressure (Ptotal) of a mixture of ideal gases is equal to the sum of the partial pressures (Pi) of the individual gases in that mixture. https://t.co/N15okQwn6W
