Overview

The Deltabar FMD77 differential pressure transmitter with metal sensor uses a one-sided diaphragm seal or diaphragm seals on both sides with a capillary on the low pressure side. 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.


Benefits

  • Large variety of different process connections and membrane materials

  • Highest safety due to gas-tight feedthrough with capabilities up to SIL2/3, certified to 
    IEC 61508

  • New TempC Membrane minimizes influences of ambient and process temperature fluctuations

  • Easy menu-guided commissioning via local display, 4 to 20 mA with HART, PROFIBUS PA, FOUNDATION Fieldbus

  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics

  • Cost savings with modular concept for easy replacement of sensor, display or electronics

  • Seamless and independent system integration (HART/PA/FF)


Application

For level, volume or mass measurement in liquids.

  • Process connections: Threads and flanges

  • Temperature: -70 to +400°C (-94 to +752°F)

  • Measuring ranges: +100mbar to +16bar (+1.5 to +240psi)

  • Accuracy: ±0.075%

  • International explosion protection certificates, overfill prevention WHG, hygienic approvals, marine approvals, SIL
