Ambient temperature -20…80 °C:
Nominal range 1-16 bar, 0.1 %/10K, max. 0.3 %
Nominal range 0.25 bar, 0.15 %/10K, max. 0.4 % |

Ambient temperature -40…-20 °C:
Typical 0.2 %/10K |
| Temperature influence, process connection: |
The temperature influence depends on several parameters, e.g. diaphragm di-ameter, diaphragm material, capillary length, capillary diameter, systeme filling, etc.
We provide a detailed error analysis upon request. |
