  • Version DMU 14 FG Ex with Ex approval for zone 0
  • ideal for process engineering
  • high accuracy of ± 0.1 %
  • either die cast housing (DG) or field housing (FG)
  • Turn down 1:10
  • Local display

The intelligent pressure transducer DMU 14 DG EX with die cast aluminium housing provides very high accuracy and a turn down function for measuring range selection and is an ideal solution for process engineering applications. The version DMU 14 FG EX with a stainless steel field housing is perfectly suitable for applications in the pharmaceutical and food industries. The devices come with HART® communication.
