Specifications
Non-linearity (per IEC 61298-2) See test report
Relationship to the mounting position For measuring ranges < 1 bar (15 psi), an additional zero offset of up to 0.15 % applies
Non-repeatability ≤ ±0.1 % of span
Temperature hysteresis 0.1 % of span at > 80 °C (176 °F)
Long-term drift (per IEC 61298-2) ≤ ±0.1 % of span
≤ ±0.2 % of span (with special measuring ranges and measuring ranges < 1 bar (15 psi))
Temperature error For calibration temperature 15 ... 25 °C (59 ... 77°F)
-20 ... +80 °C: ≤1 % of span
-30 ... +100 °C: ≤1.5 % of span
For measuring ranges < 1 bar (15 psi), special measuring ranges and instruments with an
increased overpressure limit the respective temperature error increases by 0.5 % of span
