<strong>Deltabar</strong> S<br />
Performance characteristics – ceramic process isolating<br />
diaphragms<br />
Reference accuracy –<br />
<strong>PMD70</strong>, <strong>FMD76</strong><br />
The reference accuracy comprises the non-linearity (terminal based), hysteresis and non-reproducibility as per<br />
IEC 60<strong>77</strong>0. The data refer to the calibrated span.<br />
The following applies for the root-extracting characteristic curve: The accuracy data of the <strong>Deltabar</strong> S are taken<br />
into the accuracy calculation of the flow rate with a factor of 0.5.<br />

Total performance –<br />
<strong>PMD70</strong>, <strong>FMD76</strong><br />
The "Total performance" specification comprises the non-linearity including hysteresis, non-reproducibility, the<br />
thermal change of the zero point as well as the influence of the static pressure (p st = 70 bar (1050 psi)).<br />
All specifications apply to the temperature range –10 to +60 °C (+14 to +140 °F) and a turn down of 1:1.<br />
