See order details.
Material stainless steel mat.-no. 1.4301 (304)
System filling
See order details; further fillings upon request.
Further details about pressure transmission fluids see general technical information TA_038.
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, see table.
