  Basic body: stainless steel mat.-no. 1.4435 (316L)
System filling
See order details; further fillings upon request.
Further details about pressure transmission fluids see general technical information TA_038.
Measuring device connection
See order details.
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.
With measuring device connection approx. 0.3 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.
