Hydrostatic
Level measurement
Deltapilot FMB50

Compact pressure sensor with the Contite measuring cell for hydrostatic level measurement

The compact Deltapilot FMB50 transmitter with the condensate resistant Contite measuring cell is typically used in the process and hygienic applications.
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.

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 menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus

• International usage thanks to a wide range of approvals

Field of application

For level and/or pressure measurement.

• Process connections: Thread, flanges and flush-mounted hygienic connections

• Process temperature: –10 to +100°C (14 to 212°F) (+135°C (275°F) for 30 minutes maximum)

• Measuring range: 0.1 to 10bar (1.5 to 150psi)

• Accuracy: ±0.2%, ±0.1% (option)

• International explosion protection certificates, overfill prevention WHG, SIL, hygienic certificates
