What Is an Oxygen Depletion Sensor?

An Oxygen depletion sensor can be found in a variety of industrial applications from automotive manufacturing to oil and gas refineries. These sensors are designed to help companies protect employees by ensuring the proper mix of gas and vapors is being used in confined spaces. Oxygen depletion monitors can be used to alert personnel when oxygen levels drop, and they can also be programmed to turn on a variety of devices like alarms or fans.

What is the oxygen depletion sensor test?

Most oxygen depletion systems use zirconium oxide oxygen sensors to determine the level of oxygen in a fixed sample of gas. These sensors generate voltage build up as oxygen ions pass through the sensor layer. Rich mixtures will generate a higher voltage as more oxygen ions travel through the sensor, while lean mixtures will create a lower voltage. The difference in voltage causes the oxygen sensor to respond and detect changes in gas composition.

These sensors are very durable and can withstand the harshest working conditions. However, they are prone to failure as a result of exposure to certain chemicals or gases. For example, leaded gasoline can contaminate the sensor and cause it to fail prematurely. In this case, you will notice that the sensor tip is discolored with a light rust color.
