ENDRESS+HAUSER  PMP71-ACA1F11GAAAA

Applications

The device is used for the following measuring tasks:

• Absolute pressure and gauge pressure measurement in gases, steams or liquids in all areas of process engineering and process measurement technology
• Level, volume or mass measurements in liquids
• High process temperatures
  • up to 150 °C (302 °F) without diaphragm seal
  • up to 400 °C (752 °F) with typical diaphragm seals
• High pressures up to 700 bar (10 500 psi)
• MID part certificate according to OIML R117-1 Edition 2007 (E) and EN 12405-1/A1 Edition 2006

Your benefits

• Very good reproducibility and long-term stability
• High reference accuracy up to ±0.025 %
• Turn down up to 100:1, higher on request
• Used for process pressure monitoring up to SIL 3, 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

Measuring Principle

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Advantages:

• Can be used for process pressures up to 700 bar (10500 psi)
• High long-term stability
• Guaranteed overload resistance up to 4 times the nominal pressure
• Secondary containment for enhanced integrity
• Significantly reduced thermal effect e.g. compared to diaphragm seal systems with capillaries
