How Can a Sensor Accurately Control Inflation to 2 PSI?

AI Thread Summary
To accurately control inflation to 2 PSI in a small 6-liter inflatable, a sensor or gauge is needed to replace the current mechanical timed relay system. The goal is to have a reliable method for detecting pressure and stopping inflation precisely at the desired level. Suggestions include using a simple mechanical pressure regulator for this purpose. The discussion invites questions and comments to explore effective solutions. Accurate pressure control is crucial for the design's success.

Hello all,

I am trying to design a system with a sensor that can detect when an inflatable is inflated to 2 PSI. I am trying to inflate something small, around 6 liters. I currently have a system that uses a solenoid, the compressed air, and a mechanical timed relay that tells the system when to stop inflating. The issue is that i want to make it using a sensor or gauge to tell the system to stop inflating at exactly 2 PSI.

Please let me know if you can help. All questions, comments, or suggestions are welcome.

Thanks

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
