Crusher pressure measurements (e.g. CUP, LUP) are an expression of the entire area under the pressure curve. Transducer pressure measurements (i.e PSI) are an expression of the single highest amplitude of pressure in the pressure curve.
Unfortunately, crusher pressures are sometimes inaccurately given as PSI. They aren't, and this kind of nonsense just confuses the issue.
Crusher methodology measurements and transducer methodology measurements cannot be meaningfully compared, nor can a pressure measurement from one method be meaningfully converted to a measurement in the other method.
