Pressure Reference
Definition
Output is calibrated to be proportional to the difference between applied pressure and a fixed reference to perfect
Absolute
vacuum (absolute zero pressure).
Sensor construction is identical to the absolute version with a built in reference at zero pressure in order to mini-
mize measurement error over temperature. The output is calibrated to be proportional to the difference between

applied pressure and a reference of 1 standard atmosphere (1.013 barA | 14.7 psiA). Example: 100 psi sealed
gage has a calibrated pressure range from 14.7 psi absolute to 114.7 psi absolute.
Sealed gage option only available in pressure ranges at or above 8 bar | 100 psi.
