3.5 Accuracy specifications

Accuracy at reference conditions
Standard
Option
1) Only for measuring ranges ≥ 0.25 bar
Including non-linearity, hysteresis, zero offset and end value deviation (corresponds to measured error per
IEC 61298-2). Calibrated in vertical mounting position with process connection facing downwards.
Non-linearity (per IEC 61298-2): ≤ ±0.2 % of span BFSL
Non-repeatability: ≤ 0.1 % of span
Long-term stabilty at reference conditions: ≤ ±0.2 % of span/year
Temperature error in rated temperature range
Rated temperature range: 0 ... 80 °C (32 ... 176 °F)
Mean temperature coefficient of zero point:
Measuring range > 0.25 bar: ≤ ±0.2 % of span/10 K
