Nhut_Hien Posts: 23 Rating: (0)	How about if I choose SS316 with PTFE coating for this? With pressure up to 6 bar and temperature <100 and the others >100 C. Degree. And one more problem: the pressure transmitter will be installed on pipe with the smallest diameter 38mm. Which process connection can be used in this case? And we attach the detailed specification. Please advise us. Attachment 00.Spec.Pressure Transmitter list.pdf (204 Downloads)
