What is the pressure in instrument air supply?

As an instrumentation engineer with experience in the process industry, I can share that the pressure in the instrument air supply is typically maintained between 80 to 120 psi (5.5 to 8.3 bar). This range is essential for ensuring the reliable operation of pneumatic instruments and control systems.

Maintaining a consistent pressure within this range helps avoid issues such as signal transmission delays and control valve malfunctions. In my experience, it’s also important to have a well-maintained air compressor and dryer system to ensure the air supply is clean and dry, preventing any potential damage or inaccuracies in instrumentation.

Regular monitoring and maintenance of the air supply system can help prevent downtime and ensure optimal performance of the control systems.
