Deltabar FMD77

Deltabar FMD77

The Deltabar FMD77 differential pressure transmitter with piezoresistive sensor and internal welded metallic membranes and one diaphragm seal to the process is typically used in the process industry for continuous level measurement in liquids. The integrated HistoROM data module makes the management of process and device parameters easy. Designed according to IEC 61508 for use in SIL3 safety applications.


  • Overload-resistant and function-monitored
  • Very good reproducibility and long-term stability
  • HistoROM data backup for instrument settings and measured values
  • Developed and designed according to IEC 61508, approved for use in SIL3 safety applications (min., max., range)
  • Quick commissioning thanks to quick setup menu with extensive diagnostic functions
  • Easy and safe menu-guided product configuration: On-site via display module, 4 to 20mA with HART, PROFIBUS PA, or FOUNDATION Fieldbus
  • Modular design for dP and pressure platform, e.g. replaceable display, universal electronics
