Measuring device connection
| See order details. |
| Material stainless steel mat.-no. 1.4301 (304) |
System filling
| See order details; further upon request. |
| Further details about pressure transmission fluids see general technical information TA_038. |
Hygienic design
| The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3. |
| In case of choosing the additional feature HY, we guarantee the following surface roughness values: |
| Diaphragm foil: Ra ≤ 0.38 µm Laser welds: Ra ≤ 0.76 µm Turned parts: Ra ≤ 0.76 µm |
| Further versions of hygienic design upon request. |
Temperature error
| In order to optimise the system we provide a detailed error calculation upon request. |
Weight
| See data sheet |
Installation instructions
| For diaphragm seals with clamp design an operation outside the permissible nominal pressure range is only permitted when using suitable clamping rings. Please note DIN 32676 on temperature resistance. |
| Further information about diaphragm seals see general technical information TA_031. |
| Flame arrester MF21xx for connection of measuring devices to zone 0 see data sheet D6-025. |
