The device is used for the following measuring tasks:
• Flow measurement (volume flow or mass flow) in conjunction with differential pressure sensors in gases, vapors and liquids
• Level, volume or mass measurements in liquids
• High process temperatures up to 400 °C (752 °F) possible with diaphragm seal mount
• Very good reproducibility and long-term stability
• High reference accuracy up to 0.035 %
• Turn down up to 100:1, higher on request
• Used for flow and differential pressure monitoring up to SIL3, certified to IEC 61508 by TÜV SÜD
• High level of safety during operation thanks to function monitoring from the measuring cell to the electronics
• The patented TempC membrane for the diaphragm seal reduces measured errors caused by environmental and process temperature influences to a minimum
• Easy electronic replacement guaranteed with HistoROM®/M-DAT
• Uniform platform for differential pressure, hydrostatics and pressure (Deltabar S – Deltapilot S – Cerabar S)
• Practical user navigation for quick and easy commissioning
• Extensive diagnostic functions
• Cost-effective installation with Deltabar S FMD77, capillary on low-pressure side
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.
