An oxygen sensor is a device that measures the amount of oxygen in a gas mixture. It is used in a variety of applications, including automotive emissions control, industrial process control, and medical diagnostics. Oxygen sensors are typically classified into two types: electrochemical and zirconia. Electrochemical oxygen sensors are based on the principle of electrochemistry, while zirconia oxygen sensors are based on the principle of solid-state ionics.
Oxygen sensors are an important part of many different systems. In automotive emissions control, oxygen sensors are used to measure the amount of oxygen in the exhaust gas. This information is used to control the air-fuel ratio of the engine, which helps to reduce emissions. In industrial process control, oxygen sensors are used to measure the amount of oxygen in a gas mixture. This information is used to control the process conditions, which can help to improve efficiency and safety. In medical diagnostics, oxygen sensors are used to measure the amount of oxygen in a patient’s blood. This information is used to diagnose and treat a variety of medical conditions.
