ENDRESS+HAUSER  FMD72-AA28AAA1F1FGABCBCGCJGCJA1

Application

The Deltabar FMD71/FMD72 is used to measure the differential pressure or level, volume or mass of liquids in pressurized or vacuum vessels

Your benefits

The electronic differential pressure system eliminates traditional mechanical issues resulting in greater process availability and reliability

• Safety risks are minimized with the electronic differential pressure system architecture and design
• Lowest total cost of ownership due to reduced installation time, maintenance, downtime and spare requirements, downtime and spare requirements.
• Multivariable level measurement: HART-based differential pressure, head pressure and sensor temperatures from one system
• Continuous health indication of the entire system via HART-based diagnostic
• High reproducibility and long-term stability
• Overload-resistant and function-monitored

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 40 bar (600 psi)
• Fully welded process isolating diaphragm
• Small, flush-mounted process connections
• Significantly reduced thermal effect e.g. compared to diaphragm seal systems with capillaries
