Differential pressure transmitter with metal sensors

Overload-resistant and function-monitored; Communication via

HART

Your benefits

The electronic differential pressure measurement system eliminates issues of traditional differential pressure measurements using impulse lines or capillaries:

• Eliminate measurement drift due to ambient temperature changes

• Eliminate line condensation or evaporation events (dry/wet leg inconsistencies) and plugging events

• No high cost of heating impulse lines to prevent freezing (installation, energy)

• Eliminate tubing and connection leaks often seen with traditional systems

• 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

• Intuitive menu-driven installation

• Color-coded wiring

• High reproducibility and long-term stability

• High reference accuracy of individual sensors: 
  up to ±0.075 %,

  as PLATINUM version: ±0.05 %

• Increased process availability and reliability

• Safety risks are minimized with the new electronic differential pressure system architecture and design

• Lowest total cost of owner ship due to reduced installation time, maintenance downtime and spare requirements.

应用领域

The Deltabar FMD72 is used to measure the level, volume or mass of liquids in pressurized tanks. The system compromises two sensor modules and one transmitter. One sensor module measures the hydrostatic pressure (high pressure) and the other one the head pressure (low pressure). The level (electronic differential pressure) is calculated in the transmitter using these two digital values.
