Applikationsområde

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.

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

Fördelar

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)
