Further materials upon request
  Basic body: Stainless steel mat.-no. 1.4404/1.4435 (316L)
Process connection
Design: Sanitary connections design with union nut or threaded coupling:
- DIN 11851
- IDF
- SMS
Nominal pressure/nominal width: See table
The sealing is not included in the scope of delivery.
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.
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.
Material stainless steel mat.-no. 1.4301 (304)
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.
Further information about diaphragm seals see general technical information TA_031.
