• Proof pressure - maximum allowable pressure without a shift in calibration
• Burst pressure - sensor damaged or destroyed; some risk of personnel injury
• Absolute ranges - the data for the 30 PSI / 2.0 Bar, 150 PSI / 10 Bar and 300 PSI / 20 Bar ranges also applies to the
absolute pressure versions of those ranges.
