Technical Characteristics and Environmental Resilience
-
Condensate-Resistant Contite Cell: The measuring cell is hermetically sealed against the electronics, preventing moisture and condensation from interfering with the sensor. This ensures long-term stability and accuracy even in “steamy” environments like boiling kettles or washdown areas.
-
High Precision: With a standard reference accuracy of ±0.2% (and a ±0.1% high-precision option), the FMB50 provides the reliable data needed for inventory control and sensitive process monitoring.
-
Independent of Foam: Unlike ultrasonic or radar sensors, hydrostatic measurement relies on pressure. This means that thick layers of foam on the liquid surface have no impact on the accuracy of the level reading.
-
Modular Concept: The device features a modular design that allows for the easy replacement of the display or electronics without removing the transmitter from the process, reducing maintenance downtime.
-
Safety and Integration: Certified for use in SIL2 safety systems and WHG overfill prevention, it integrates seamlessly into modern control environments via HART, PROFIBUS PA, or FOUNDATION Fieldbus.

Primary Applications
-
Food and Beverage: Level measurement in milk storage, fruit juice pasteurizers, and brewery vessels where CIP/SIP cycles are frequent.
-
Paste-like Media: Reliable monitoring of thick liquids, sauces, and yogurts in mixing and process tanks.
-
Pharmaceutical Processing: Accurate level control in sterile vessels where hygienic connections and high precision are required.
-
Open or Closed Containers: Suitable for both vented storage tanks and pressurized process vessels.
-
High Humidity Environments: Ideal for cooling towers, cold storage tanks, or any application where condensation is a persistent issue for standard sensors.
