Shielding gas sensor for room monitoring
A shielding gas sensor measures the oxygen content in enclosed spaces and gives warnings about asphyxiation risk from heavy shielding gases like argon or carbon dioxide.
Physical-Chemical Mechanism of Action
A shielding gas sensor measures the oxygen content in the air. It uses an electrolyte that generates an electrical voltage when in contact with oxygen. The lower the oxygen content, the lower the voltage.
Metallurgical Relevance & Welding Risks
In enclosed containers or spaces, welding with heavy shielding gases like argon or carbon dioxide can drastically reduce the oxygen content. A lower oxygen level can pose an acute suffocation hazard, especially for people with respiratory issues or other health problems. It is therefore crucial to monitor the oxygen concentration regularly.
Workshop Practice & Action Instructions
Install the shielding gas sensor in enclosed spaces or containers where heavy shielding gas is used. Make sure the sensor is connected to a power source and an alarm system. Check the sensor's functionality regularly and ensure proper calibration. If an alarm sounds, leave the area immediately and inform others.
