First of all... wow. We spent the first couple weeks planning to lift, until we got fed up with the 80" cylinder, then said "what the heck" and started putting together launch prototypes last week. We managed to get the ball onto the overpass using two 1.5 x 8" cylinders... but without any preload. The only catch was that we used the 120psi feed from the shop compressor, so it was back to the drawing board. This weekend involved sitting around with the calculator, spreadsheet, and a demo copy of Working Model to calculate what we'd need to do it with 1.5x8" cylinders as... for some reason... we have five of them kicking around the shop. Lo and behold, the calculations came out very close to your observations. Thanks!

Now, perhaps, I can return the favour, by suggesting that the device you are looking for is called a "pressure transducer" and that a quick search of the forums here brings up a link to here where you can see a picture of one that was apparently in the 2006 KOP. It's possible you have one sitting in your shop and don't know of it!

As for sending the data back and displaying it, I suspect your programming team is on top of how to send it, and perhaps someone is building a custom dashboard in labview?

Thanks again... I feel so much more confident with our design knowing that our calculations are not entirely off-base!
