Peak pressure recording system

[SpudStuff]

to make a pressure guage thats records the highest pressure acheved get a guage and a check valve that threads onto it. then the pressure is trapped in the valve recording the highest pressure

Genious

What would be the point of that? How would you release it? And if you really wanted to know the peak pressure just look at it while it's charged.

hmm... maybe im confuses but, dont most pressure guages have a little red needle that rides on the black needle cause it has a little metal flange sticking down, and the red needle is reset by a little knob, so it stays up after the pressure releases? Honesty i dont under stand the idea, this is what i interpret, you have pressure in the chamber, and a gauge that shows how much pressure you have stored, and a one way (check) valve running into another gauge that also shows how much pressure you have .... can you explain it to me

[Atlantis]

He basically means that the pressure rises in the chamber and the gauge. The chamber empties but due to the check valve between the gauge and the chamber, the air in the gauge stays put.

[Pete Zaria]

I'd use a T valve with the chamber on the bottom, a pressure release valve on the side, and the gauge on the top. That way you can easily reset the gauge. It sounds like a good idea to me.

Peace,

umm, i think he means to see how much pressure a combustion generates during fire. its kind of hard to look at ur gauge change when the chamber is only pressurized for a second or two.

[saladtossser]

they have those, like those pen style pressure gauges for car tires.

you can also use mcmaster # 4031K13

[schmanman]

someone has already done that with a hybred. and like Pete Zaria said use a t at the bottom of the gauge,exceot put a ball valve on the other part of the t instead.

But good thinking

[LucyInTheSky]

"someone has already done that with a hybred."

hybred? bread on a shelf?

[frogy]

Lol.... High Bread, I hate when that happens...

You can't really use this supper accuratel due to pressure shock that'll ruin the gauge, if your trying to measure a hybrid your going to need like a 1000 psi gauge...

[BC Pneumatics]

Boogie built this into the manifold on hus hybrid.

[Velocity]

many people have done this... it is not a new concept.

I remember that lucky13 did this on his hybrid, somewhere in these forums, and measured a 4X mix... check it out in the hybrid section

[M3NT4L]

itd be cool if you could get a high speed camera that shoots like 100 frames per sec. and film the gauge to see the spike and highest point.

[Shrimphead]

I don't think that they make "high-speed" cameras. At least not consumer cameras. Although with some you can adjust the frames per second. But if it takes too many frames then the picture looks unnatural.

"I don't think that they make "high-speed" cameras."
Errr, yea they do.
