3.6 Time response
Settling time ≤ 2 ms (≤ 10 ms, for medium temperatures below -30 °C)
3.7 Accuracy data
Accuracy at reference conditions 0.50 % of span
Optional: 0.25 % (only for measuring ranges ≥ 0.25 bar and ≤ 1,000 bar)
Including non-linearity, hysteresis, zero oset and end value deviation
(corresponds to measured error per IEC 61298-2).
Non-linearity (IEC 61298-2) ≤ 0.2 % of span BFSL
Non-repeatability ≤ 0.1 % of span
Mean temperature coecient of zero
point (0 ... 80 °C)
Measuring range ≤ 0.25 bar: ≤ 0.4 % of span/10 K
Measuring range > 0.25 bar: ≤ 0.2 % of span/10 K
Mean temperature coecient of span
(0 ... 80 °C)
≤ 0.2 % of span/10 K
Long-term stability at reference
conditions
≤ ±0.2 % of span/year
Adjustability of zero point and span Adjustment is made using potentiometers inside the instrument.
Zero point and span: ±5 %
