Cat scales don't use air pressure to measure the weight. They use load sensors which are basically a piece of metal that gets "squashed" when you drive on them. The computer reads the "amount of squashing" to give the weight.
Um, yeah.
What I meant was, I've scaled a bunch of loads and also taken the pressure gauge readings on each axle for those same 100 loads. i.e 80 psi on the rear axle of trailer = 40,000 lbs. Then I made a chart using all these loads so whatever the psi is, we can get a pretty good idea what the axle weights are. If it's sitting level.
