Re: Calibrate Pressure Switch?

The pressure switch that is being discussed was resettable in seconds, without tools, to a max of 145 psi. For those reasons and others that I discussed with the team, it neither meets the rules, the Q&A nor the intent.

Frank, the calculation I was looking for is the pressure volume conversion. So with two Clippard 41 cu. in. tanks, the conversion to 60 psi results in 157 cu in. @115 psi and 164 cu. in. @ 120 psi. About 4% increase in volume at 60 psi.

Sorry I didn't answer sooner, I was at the Minnesota State HS Champs this weekend.
