ENDRESS+HAUSER  PMD75-ACA7D11BAAA

Applications

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

Your benefits

• 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

Measuring Principle

The process isolating diaphragms are deflected on both sides by the acting pressures. A filling oil transfers the pressure to a resistance bridge (semiconductor technology). The change in the bridge output voltage, which depends on the differential pressure, is measured and processed

Advantages:

• Standard operating pressures: 160 bar (2 400 psi) and 420 bar (6 300 psi)
• High long-term stability
• Very high single-sided overload resistance
