3.4 Accuracy

The model A-10 is optionally available with an improved non-linearity. Depending on the version the

following values apply.

Non-linearity per BFSL (IEC 61298-2) Standard

≤ ±0.5 % of span

Option

≤ ±0.25 % of span

Non-repeatability ≤ 0.1 % of span ≤ 0.1 % of span

Long-term drift (per IEC 61298-2) ≤ ±0.1% of span ≤ ±0.1% of span

Signal noise ≤ ±0.3% of span ≤ ±0.3% of span

Settling time < 4 ms < 4 ms

Temperature error at 0 ... 80 °C Typical: 1 % of span

Maximum: 2.5 % of span

Typical: 1 % of span

Maximum: 2.5 % of span

Measuring deviation of the zero signal Typical: ≤ ±0.5 % of span

Maximum: ≤ ±0.8 % der Spanne

Typical: ≤ ±0.15 % of span

Maximum: ≤ ±0.4 % of span

Accuracy at room temperature

≤ ±1 % of span ≤ ± 0.5 % of span,

≤ ± 0.6 % of span (at 0 ... 5 V)

1) 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.

3. Specications

3.6 Operating conditions

Ingress protection (per IEC 60529)

The ingress protection depends on the type of electrical connection (see table under 3.7 "Electrical

connections, specications").

Vibration resistance

10 g (IEC 60068-2-27, under resonance)

20 g available on request

Shock resistance

500 g (IEC 60068-2-6, mechanical)
