Oxygen cleaning process Strict cleaning to ensure that the sensor is clean and free of oil, corrosion, scaling, particles and other impurities. Oxygen cleaning pressure sensor completely solves the potential risk of oxygen combustion or explosion caused by sensor oil contamination during oxygen pressure measurement.
Sino-Inst manufactures pressure sensors and transmitters that are cleaned for use with oxygen.

Oxygen Cleaning Pressure Sensor

What is oxygen cleaning?

Oxygen cleaning is like giving a deep spring clean to equipment that comes in contact with oxygen. Imagine you’re tidying up your room. You’d clean all the visible dirt, right? But what about the tiny dust particles hiding in corners or under your bed? With a regular clean, you might miss them. But with a ‘deep clean,’ you’d make sure to get rid of them too.

Oxygen cleaning is this ‘deep clean’ for equipment. It makes sure to remove all tiny bits of dirt, oil, and other stuff that could cause a big problem if they catch fire in an oxygen-rich environment. So, by doing this deep clean, we’re making the equipment super safe to use with oxygen!

Why is Oxygen Cleaning important?

Imagine you’re making a small campfire. You add some sticks and leaves, and you have a nice little fire going. Now, imagine you pour a bucket of gasoline on it. Boom! You now have a massive, raging fire that’s hard to control. This is similar to what can happen in oxygen-rich environments. Oxygen itself isn’t flammable, but it makes other things burn really quickly and intensely.

Now, picture tiny particles of oil, grease, or dirt on your equipment. If these particles caught fire in an oxygen-rich environment, it could lead to a serious accident or even an explosion. That’s why we need to make sure our equipment is super clean before we use it with oxygen.

In other words, oxygen cleaning is crucial because it removes these tiny particles and makes our equipment safer. So, it’s not just about cleanliness—it’s about safety, reliability, and peace of mind. That’s why oxygen cleaning is not just important, it’s essential!

Oxygen Cleaning Pressure Sensor Application Industry

Oxygen cleaning of pressure sensors is essential in various industries where safety and precision are crucial. Let’s look at some of these:

  • Aerospace: In the aerospace industry, oxygen systems are often used for life support in spacecraft and airplanes. Any equipment, including pressure sensors, used in these systems must be thoroughly cleaned to ensure safety and reliability.
  • Medical: Medical devices, particularly those related to oxygen therapy and anesthesia, often require oxygen-cleaned pressure sensors to prevent any risk of combustion and ensure patient safety.
  • Oil and Gas: The oil and gas industry frequently uses oxygen for various processes, including refining and production. Oxygen-cleaned pressure sensors are necessary to ensure these processes are conducted safely and efficiently.
  • Chemical Processing: In chemical processing plants, oxygen is often used in various processes, and any contaminants could potentially cause harmful reactions. Therefore, pressure sensors used in these environments are typically oxygen-cleaned.
  • Scuba Diving Equipment: Scuba diving equipment, such as rebreathers, often uses pressure sensors that need to be oxygen-cleaned. This ensures the safety of the diver by preventing combustion under the sea.
  • Firefighting Equipment: Oxygen is often used in breathing apparatus for firefighters. The pressure sensors used in this equipment need to be oxygen-cleaned to ensure the safety of the firefighters.

Remember, oxygen cleaning isn’t just about cleanliness—it’s about safety and efficiency in operations. It’s an essential step that allows various industries to perform their tasks confidently and without risk.



Oxygen cleaning is a process that thoroughly cleans components that come into contact with oxygen. It removes contaminants such as grease, oil, dust, and other particles to prevent combustion in oxygen-rich environments.

Various methods are used for oxygen cleaning, including ultrasonic cleaning, steam cleaning, chemical cleaning, and more. The choice of method depends on the type of component and its contamination levels.

Oxygen cleaning is essential for safety. In oxygen-rich environments, even tiny particles can catch fire and cause damage. Oxygen cleaning helps to remove these particles and prevent potential hazards.

The choice of solvents depends on the type of contaminants present. Commonly used solvents include alcohol, acetone, and various commercial oxygen-cleaning agents. All cleaning agents must be thoroughly removed after cleaning to avoid further contamination.
