Technical Specifications

Applications

• Oxygen cylinder pressure monitoring
• Gas welding & oxy-fuel cutting systems
• Industrial gas regulator systems
• Metal fabrication workshops
• Medical oxygen supply systems
• Laboratory gas control systems
• HVAC gas pressure monitoring

Working Principle

The Bourdon tube inside the gauge deforms when oxygen pressure changes. This mechanical movement is transmitted to the pointer, providing real-time pressure indication without electricity

Safety Notice

Oxygen pressure gauges must be oil-free because oxygen supports combustion. Any contamination with oil or grease may cause dangerous reactions. This gauge is manufactured under strict oxygen-safe production standards.

FAQ

What is YO50 oxygen pressure gauge used for?

It is used for oxygen cylinder monitoring, welding systems, and industrial gas control.

Why must oxygen gauges be oil-free?

Oxygen reacts strongly with oil or grease, which may cause fire or explosion risks.

Is brass safe for oxygen pressure gauges?

Yes, brass is widely used in oxygen applications due to its stability and safety.

Can it be used for other gases?

Yes, but it is specifically optimized for oxygen systems.
