ENDRESS+HAUSER  PMD55-AA22AA27BGBHA4A1A

Applications

The device is used for the following measuring tasks:

• Flow measurement (volume or mass flow) in conjunction with primary elements in gases, vapours and liquids
• Level, volume or mass measurement in liquids
• Differential pressure monitoring, e.g. of filters and pumps

Your benefits

• Very good reproducibility and long-term stability
• High reference accuracy: 0.10 % as PLATINUM version: up to 0.075 %
• Turn down up to 100:1
• Compact transmitter design
• Fast commissioning via DIP switches
• Uniform platform for differential pressure, hydrostatics and pressure (Deltabar M – Deltapilot M – Cerabar M)
• Simple, fast commissioning through a user interface designed for real-world applications
• Used for process pressure monitoring up to SIL 2, certified to IEC 61508 Edition 2.0 and IEC 61511 by TÜV NORD

Measuring Principle

The metal separating diaphragms (4) are deflected on both sides by the acting pressures p1 and p2. A filling oil (3) transfers the pressure to a resistance circuit bridge (semiconductor technology). The differential- pressure-dependent change of the bridge output voltage is measured and further processed.
