DMD 331

Code: DMD 331
  • differential pressure 0...20 mbar up to 0...16 bar
  • accuracy: 0.5% FSO
  • 2 piezoresistive stainless steel sensors
  • media separation through stainless steel 1.4435 diaphragm
  • differential pressure wet / wet
  • permissible static pressure -one sided- up to 30 times of differential pressure range
  • compact design
  • IS-version
  • mechanical robust and relieable at dynamic pressure as well as shock and vibration
  • areas of application: mechanical and plant engineering, energy industry

The DMD 331 is a differential pressure transmitter for industrial applications and is based on a piezoresistive stainless steel sensor, which can be pressurized on both sides with fluids or gases compatible with SST 1.4404 (316L) and 1.4435 (316L).

The compact design allows an integration of the DMD 331 in machines and applications with limited space. The DMD 331 calculates the diffe-rence between the pressure on the positive and the negative side and converts it into a proportional electrical signal.
