Field of application
The Deltapilot FMB52 is a cable version including a fixed process connection. This device with the Contite measuring cell is typically used in the process and environmental industries. It is made for level measurement in liquid and paste-like media in open or closed containers and is unaffected by possible foam formation. For use in SIL2 safety systems.
For level measurement.
Process connections: Threads and flanges
Temperature: With PE cable: -10 to +70°C (+14 to +158°F),
with FEP cable: -10 to +80°C (14 to 176°F)
Measuring range: 0.1 to 10bar / 100m H2O (1.5 to 150psi / 300ft H2O)
Accuracy: ±0.2%, ±0.1% (option)
International explosion protection certificates, overfill prevention WHG, SIL, drinking water approval
Benefits
Hermetically sealed Contite measuring cell with condensate-resistance, high reference accuracy: ±0.2%, optionally ±0.1% and minimum temperature effects
Modular concept for easy replacement of display or electronics
Seamless and independent system integration (HART/PA/FF)
Easy and safe menu-guided operation: On-site via display module, via 4 to 20mA with HART, via PROFIBUS PA, via FOUNDATION Fieldbus
International usage thanks to a wide range of approvals
