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.
I will have to respectfully disagree with this statement. Both systems, Crusher or Transducer, measure the Max pressure. "IF" each in a system where you were measuring static pressure they would both read the same. The reason they do not read the same in this application is the transducer reads instantaneously while it takes a period of time to collapse the crusher. Admittedly it is an extremely short time, but never-the-less the time of the max pressure being applied is not enough to fully compress the crusher. The crusher will never show a higher pressure than the transducer, assumong it is properly calibrated.
