  • for chemical and process engineering applications
  • measuring system fully welded to housing
  • extremely robust design
  • can be used in case of heavy vibrations and high, dynamic pressure loads
  • tightness-tested with helium
  • DNV- and GOSSTANDART-certified
  • Ex version (optional)

For corrosive gaseous and liquid media which are not highly viscous and do not crystallise; suitable for corrosive environments. For measurements in areas with high vibration levels and high, dynamic pressure loads.
! For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)!
