  • The Deltapilot FMB53 is a cable version with mounting clamp. This device with the Contite measuring cell is typically used in the environmental industries. It is made for level measurement in liquid and paste-like media in open or closed containers and 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

    For level measurement.

    • Process connection: Suspension clamp
    • 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
    • Measuring principle


    • Characteristic

      Pressure transmitter for pressure or hydrostatic level measurement with flush mounted metallic CONTITE measuring cell: 
      – hermetically welded
