Pressure measuring principle

The new TempC Membrane

Differential pressure transmitter with two diaphragm seals for differential pressure and level

The Deltabar FMD78 differential pressure transmitter with metal sensor uses two capillary diaphragm seals. Typically used in process and hygiene applications for continuous measurement of pressure differences in liquids, vapors, gases and dusts. 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.

  • Edut

    • Large variety of different process connections and membrane materials

    • New TempC Membrane for diaphragm seals: Minimum temperature effects and short recovery times

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

  • Käyttöalue

    For differential pressure, level, volume or mass measurement in liquids.

    • Process connections: Threads, flanges, pancake and hygienic connections

    • Process temperature: -70 up to +400°C (-94 to +752°F)

    • Measuring ranges: 100mbar to +40 bar (1.5 to 600psi)
