المزايا التقنية الحاسمة
-
Condensate-Resistant Contite Cell: The FMB51 utilizes the hermetically sealed Contite cell, which is specifically engineered to resist the effects of condensation. This ensures high reference accuracy and minimal temperature drift, which is vital for outdoor installations or processes with varying humidity levels.
-
Mechanical Stability (Rod Design): Unlike cable-mounted sensors, the rod version provides a rigid and fixed installation. This is ideal for tanks with internal agitation or moderate turbulence where a stable sensor position is required to maintain measurement accuracy.
-
Immune to Surface Interference: Because the hydrostatic principle measures the weight of the liquid column, the FMB51 is completely unaffected by foam, gas layers, or floating debris on the liquid surface.
-
Safety and Environmental Compliance: The transmitter is designed for use in SIL2 safety systems and carries drinking water approvals and WHG overfill prevention certification, making it a trusted choice for environmental protection and water processing.
-
HistoROM Data Management: Following the modular concept, the FMB51 allows for the easy replacement of electronics or the display module. All device parameters can be stored and transferred, which simplifies maintenance and minimizes plant downtime.
-
Integrated Communication: The device integrates seamlessly into existing control systems via 4 to 20mA HART, PROFIBUS PA, or FOUNDATION Fieldbus, allowing for both local and remote commissioning.

التطبيقات الأساسية
-
Water and Wastewater Treatment: Monitoring levels in basins, reservoirs, and chemical storage tanks where condensation is frequent.
-
Environmental Protection: Reliable overfill prevention in hazardous liquid storage compliant with WHG regulations.
-
Drinking Water Management: Level measurement in clean water towers and filtration systems requiring specific material approvals.
-
Chemical Process Tanks: Measuring liquid or paste-like media in containers where a fixed rod mounting is preferred over a cable suspension.
-
Open Basins with Foam: Precise level tracking in aeration tanks or basins where surface foam makes ultrasonic or radar measurement difficult.
