Proof pressure is the max. pressure which may be applied without causing damage to the sensing element.
Full scale measurement at maximum operating pressure.
Non-linearity - the maximum deviation of measured output at constant temperature, from "Best
Straight Line"
through three points (offset pressure, full scale pressure and half scale pressure).
Temperature tested and guaranteed from at 70°C relative to 25°C. All specs. are shown relative to 25°C.
Change in output after 1 year.
Recommended o-ring 17 x 1 mm #674-70.
