Hygienic design
| The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3 (Code: 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
| With measuring device connection G1/2 D = 31: ca. 0.3 kg D = 50: ca. 0.6 kg D = 68: ca. 0.8 kg |
