What is the difference between proof pressure and over range pressure?
Over range pressure is the working pressure of the unit. That is the pressure unit can see on a daily basis without damage to the unit or compromise in repeatability. Proof pressure is the maximum pressure the unit can see on an occasional basis. Although there would be no physical damage to the unit , there may be a need to recalibrate the unit.
