Absolute pressure measuring limits from dif‐
ferential pressure series
For process temperature 60 °C < ϑ
≤ 100 °C (max. 85 °C for measur‐
ing cell
30 bar) (140 °F < ϑ ≤ 212 °F
(max. 185 °F for measuring cell
435 psi))
30 mbar a + 20 mbar a • (ϑ - 60 °C)/°C
3 kPa a + 2 kPa a • (ϑ - 60 °C)/°C
0.44 psi a + 0.29 psi a • (ϑ - 140 °F)/°F
Upper measuring limit 100% of max. range (for oxygen measurement: max. 100 bar/10 MPa/
1450 psi and 60 °C ambient temperature/medium temperature)
Lower range value Between the measuring limits (continuously adjustable)
