Differential pressure transmitter with metal sensor for measurement of pressure differences
For level, volume or mass measurement in liquids, differential pressure monitoring as well as flow measurement (volume or mass flow) in conjunction with primary elements in gases, vapors and liquids.
Process connections: Threads
Process temperature: -40 to +85°C (-40 to +185°F)
Measuring ranges: 0.25mbar to 40bar (0.0036 to 600psi)
Accuracy: ±0.05%, "Platinum" ±0.035% (optional)
International explosion protection certificates, overfill prevention WHG, SIL, hygienic approvals, marine approvals
Best accuracy, reproducibility and long-term stability
Highest safety due to gas tight feedthrough with capabilities up to SIL2/3, certified to IEC 61508
Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus
HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
Cost savings with modular concept for easy replacement of sensor, display or electronics
Overload-resistant up to 420bar / 42MPa / 6300psi, function-monitored
Seamless and independent system integration (HART/PA/FF)
Pressure measuring principle
Functional safety in process measurement
