Electronic differential pressure system utilizing two metal sensor modules and one transmitter

For differential pressure, level, volume or mass measurement of liquids in pressurized tanks and distillation columns/evaporators.

Process connections: Threads, flanges and hygienic connections

Process temperature: -40 to +125°C (-40 to +257°F), optional 250°C (480°F)

Measuring range: 400mbar to +40bar (6 to 600psi)

Accuracy: Single sensor up to ±0.05%, system up to ±0.07%

International explosion protection certificates, hygienic approvals

Eliminates traditional mechanical issues resulting in greater process availability and reliability

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

Lowest total cost of ownership due to reduced installation time, maintenance, 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

Process safety assured with small flush mounted process connections in hygienic applications

Pressure measuring principle

The new electronic dp system
