Reference Conditions Increasing characteristic, start of scale value 0 bar, stainless steel seal diaphragm,

silicon oil filling, temperature 25°C (77°F) r: span ratio (r = max. span/set span)

Error in measurement and fixed-point

setting (including hysteresis and

repeatability)

• Linear characteristic

- r ≤ 10 ≤ (0.0029 * r + 0.071)%

- 10 ≤ r < 30 ≤ (0.0045 * r + 0.071) %
