Critical Technical Advantages
-
Condensate-Resistant Contite Cell: The hermetically sealed Contite cell is the standout feature of the FMB50. It is designed to withstand the heavy condensation common in cold media applications or humid environments, ensuring high reference accuracy and minimal temperature effects where standard sensors might fail.
-
Immune to Foam and Turbulence: Because it measures hydrostatic pressure at the bottom of the vessel, the measurement remains unaffected by surface foam, build-up, or turbulent liquid surfaces, providing a much more stable level signal than top-down technologies.
-
Hygienic Integrity: With a variety of flush-mounted hygienic connections and a design that withstands temperatures up to 135°C (275°F) for short durations, the FMB50 is perfectly suited for CIP and SIP cleaning cycles in the food and life sciences industries.
-
Safety and Compliance: The device is developed for use in SIL2 safety systems and carries international explosion protection and overfill prevention (WHG) certificates, ensuring it meets the rigorous safety requirements of chemical and petrochemical plants.
-
Modular Data Management: The FMB50 utilizes a modular concept that allows for the easy replacement of the local display or electronics module without taking the instrument out of the process. This flexibility reduces maintenance costs and spare parts inventory.
-
Versatile System Integration: It supports seamless integration into all major fieldbus systems, including HART, PROFIBUS PA, and FOUNDATION Fieldbus, allowing for easy remote configuration and monitoring.

-
Cold Media Storage: Level monitoring in chilled water tanks or refrigerated storage vessels where condensation is a constant challenge for electronics.
-
Chemical Process Vessels: Hydrostatic level measurement in open or closed tanks containing liquid or paste-like chemicals.
-
Water and Wastewater: Measuring levels in reservoirs or processing tanks where reliable, drift-free performance is required.
-
Life Sciences: Monitoring purified water or ingredients in hygienic containers requiring SIL2 safety standards.
