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 approx. 0.8 kg |
