Hygienic design
The surface roughness of the wetted parts 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
With measuring device connection G1/2 approx. 0.8 kg
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.
