We tested a bunch of tank regs - here's the vid and data:

there are two tabs on the data sheet - one is output pressure for various input pressures for each reg - the other one is how much the regulator crept over 5 minutes.

and finally, here's something that amuses us:

here's an update - we tested another reg that Guerrilla provided.

The Myth reg seems to work beautifully!

check out the input:output ratio on the myth

Yea... I just noticed that. What the hell is going on there?

[sticktodrum]

That's terrible. What do you think caused that?

too much D control. not enough I control

ill explain it in a youtube video in a couple of days.

Sooo... CP can we expect a tank recharge rate test between some adjustables anytime soon?

[Dragon1291]

So ninja Wins. Coolio.
Could you continue the creep test? Espcially for the myth, cause it spikes, then goes back down, but i'm curious if it will spike up again...

we dont have a transducer, so that is the one thing we cannot measure ... yet

azreal has started posting some tank reg stuff, he has a transducer.

the three really big factors in regs are creep, input:output, and flow. we can measure the first two, which we did. we dont have anything to accurately measure flow or recharge.

[Chace365]

How does a transducer work?

it measures voltage using a computer. so you can scan the volt meter at thousands of times per second, thus you can catch very very very fast events, like recharge. gauges arn't accurate for those peaks and valleys, nor are they fast enough because they have heavy masses to move (like springs and stuff).

[Z3R0]

So in layman's terms... magic?

I thought we were measuring air flow, not electrical current?

well it measures pressure. so you stick it on the reservoir that is being vented and you can watch the pressure drop, and come back up. the time it takes is a good indicator of flow though the restriction, which is the reg.

it does this with basically a strain gauge. which is just a variable resistor, that varies with length. so the pressure pushes against the transducer and moves it a couple thou and that changes the resistance, which changes the voltage. then you can compute the pressure, and graph it.

Can I make a suggestion on the tank regs you and Bryce use?

when we can do it, sure. we dont have a transducer, and its not in the near future, so ... yeah ...

Oh. I assumed it was going to be in the near future.
Do you have an estimate as to when you can obtain a transducer?

next time we have a lot of money and the time to dink around with it and buy a DAQ. you typically need to write code and such or run Matlab or something, which i dont have a license for.

its a ways off.

This is interesting... but, the sample size (one reg per brand) is pretty small. I wish there was a way for you to test multiple ninja tanks, multiple crossfire tanks, etc. I know that's asking for a lot, but good job regardless.
