3.5 Accuracy data
Accuracy, analogue signal
≤ ±1.0 % of span
Including non-linearity, hysteresis, zero oset and end value deviation (corresponds to measured error
per IEC 61298-2). Calibrated in vertical mounting position with process connection facing downwards.
Non-linearity: ≤ ±0.5 % of span (BFSL, IEC 61298-2)
Long-term drift:≤ ±0.2 % of span (IEC 61298-2)
