Airforce Text Rex pressure gauge

[Poke-E]

I have a Sekhmet 28mm digital pressure gauge that is rated at a working pressure of 300 bar. My guns max fill is 310 bar. Does anyone think the additional 10 bar added to the tank will pose a safety issue if I used the SEKHMET gauge? It would only be an additional 145 PSI. I Believe that typically when it comes to pressure relation, things we use are typically tested at 1000 to 1,500 PSI more than what they're rated for. Just want to get everyone's opinion on this!

but you might go out of it's calibration range and then you will ruin the gauge even if it doesn't fail it will make it not accurate for any pressure.. you never want to exceed maximum pressure rating on the gauge.. normally like in hydraulic stuff we go for 3/4 the maximum pressure.. so like a system that operates 300-3500 id use a 5000 PSI gauge for best accuracy and lifespan.

I typically agree that when it comes to stuff like this, you would assume that for safety the part is designed to handle more than its rated for.

In this case I would just fill to 300 bar /4350psi. You would think it could handle it, but it does say 300 bar max working pressure. I wouldn't push the gauge. The 10 bar extra on a fill isn't going to gain you many shots, but could break the gauge. I have guns that are 310bar, 300bar, and 250 bar. While I dont fill them beyond their maximum working pressure, I do go right to the line

@markhooper I appreciate that explanation. That makes perfect sense!!
