Pressure Reference Definitions Pressure Reference Definition Output is calibrated to be proportional to the difference between applied pressure and a fixed reference to Absolute perfect vacuum (absolute zero pressure). Sensor construction is identical to the absolute version with a built in reference at zero pressure in order to minimize measurement error over temperature. The output is calibrated to be proportional to the difference 1 Sealed gage between applied pressure and a reference of 1 standard atmosphere (1.013 barA 14.7 psiA).
