Endress+Hauser

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.

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)

  • Accuracy: ±0.075%
