E+H Deltapilot FMB52 Hydrostatic Level Transmitter

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.

  • 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
