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
Temperature error
In order to optimise the system we provide a detailed error calculation upon request.
With measuring device connection approx. 0.3 kg
Further information about diaphragm seals see general technical information TA_031.
