Đặc điểm kỹ thuật và khả năng hoạt động ở vùng nước sâu của tàu
-
Condensate-Resistant Contite Cell: The sensor element is protected by a hermetic seal, preventing moisture from entering the electronics. This is critical for cable-suspended sensors where the head may stay at ambient temperature while the probe is in a warm, humid environment, which usually triggers condensation.
-
Flexible Cable Design: The cable version allows for level measurement at depths up to 100 meters (300 ft). This flexibility makes it much easier to transport and install in deep shafts or tall silos compared to rigid rod versions.
-
Foam-Independent Accuracy: As a hydrostatic pressure sensor, the FMB52 measures the weight of the liquid column. It is completely unaffected by foam, turbulence, or surface agitation that would disrupt ultrasonic or radar sensors.
-
High-Grade Cable Materials: Depending on the process requirements, the cable is available in PE (Polyethylene) for standard water applications or FEP (Fluorinated Ethylene Propylene) for higher temperatures and more aggressive chemical environments.
-
Modular and Safe: The device follows a modular design for easy electronics or display swaps. It is certified for SIL2 safety loops and carries drinking water approvals, ensuring suitability for public utility projects.
