2005 Pneumatic Kit

[Andy_Brockway]

Some pretty good pictures and descriptions of the 2005 components can be found here:

BTW, they have a great article you can download also.

nice find…i will add this stuff to my pneumatics presentation before i upload it…but it does look like we arn;t getting anything exceedingly different this year

[MikeDubreuil]

Of particular interest is the new TI 5CP3-7 pressure transducer. It appears as though the new version will be an analog pressure sensor. This would allow your software to wait before firing a pneumatic actuator until it reaches any pressure threshold your system needs. Nice job FIRST **

So, I guess we are getting a new compressor this year?

[Tristan_Lall]

Maybe I’m missing a subtlety here, but that is last year’s pneumatics kit. The compressor is the same one that’s been used since 2002 or before (I know that the 1999 compressor was different; I’m not sure about the intervening years). The TI pressure transducer was in the kit last year, and indeed, is connectable to an analog input.

I think that they’re just getting the site up and running, in anticipation of updating it as soon as the official game is released. In short, there’s nothing new to see here, yet.

I thought so at first but did we get those magnetic sensors for the cylinders in 2004? One thing for sure, they specifically mention elsewhere in the site that the 2005 FIRST Pneumatic Manual will be available shortly.

Yes, we had the option to get the magnetic reed switches with our three “free” cylinders last year. On the form from last year (pg 19) of the 2004 pnuematics manual you got to choose whether you wanted the magnetic cylinder option by adding an “M” to the front of the part number.

The pnuematics info on this 2005 site looks like last years stuff.

The magnetic sensors were optional in 2004. As for the manual being available shortly, kickoff will be taking place shortly so they may just be preparing the site.

EDIT: Doug G beat me to it.

I use the TI pressure transducers regularly. They work well unless at high temp when the temp induced error is rather high. I don’t think that part number is correct though because I can’t find the cut sheet at the TI sensors web site. The 2CP5 (custom dash #) is what I use for refrigerant applications. I will link to that cut sheet because I believe this is a similar part. I don’t usually work with the controller but what do we have for inputs? 0-5V? 4-20 mA?

I found a cut sheet last year, but it’s too large to post (pdf ~600KB). If anyone wants it I can send it as an attachment.

If you look closely, the picture of all the pneumatic parts are different. In the new…2005 one, it shows the rotary actuator in the actual picture. Last year it was available, but wasn’t on the picture diagram.

When I was making sure we had received everything in our kit, I noticed the pre-2004 pressure switch sensor is back this year. The TI analog pressure sensor is gone.

We’ve had that pressure sensor last year too and it was still required last year and probably is again. It is for making sure your compressor turns off before you go over 120 psig.

It’s too bad if the TI sensor is missing though (it was an optional sensor last year but has a lot of interesting applications). I hope it was just from your kit and not gone gone. We didn’t get ours with our kit last year. Well I guess we can still use last year’s TI this year since we didn’t use it on our previous robot.

I think you either didn’t read or totally misunderstood my post.

The TI sensor is no longer part of the kit.

[quote=Rule <R88>]The Nason Co. pressure switch must be connected to the output end of one of the Clippard tanks to sense
the tank’s pressure. The two wires from the pressure switch must be connected directly to a digital input
and ground terminals on the Robot Controller, and the controller must be programmed to sense the state
of the switch to operate the relay that powers the compressor. The Parker Pressure Vent valve must be
connected to a Clippard tank such that, when manually operated, it will vent to the atmosphere to relieve
any stored pressure. The valve must be placed on the robot so that it is visible and accessible.[/quote]

I know how they work and what they do
