Technical Characteristics and Sanitary Excellence
-
Hygienic Design and Certification: The FTL50H meets the strictest global standards, including 3-A, EHEDG, and ASME BPE. All materials are FDA-conformed, and the sensor surfaces are electro-polished and passivated to prevent bacterial growth and ensure easy cleaning.
-
Functional Safety (SIL2/SIL3): Developed according to IEC 61508, the device is suitable for high-integrity safety systems. It continuously monitors its own tuning fork for damage or corrosion, ensuring the safety function is always guaranteed.
-
Media-Independent Reliability: Whether used in milk, glucose, pharmaceutical buffers, or cleaning agents, the FTL50H requires no calibration. It accurately detects the level regardless of changes in conductivity, viscosity, or density.
-
Robust Welded Construction: The completely welded housing concept prevents the ingress of moisture or contaminants, even during high-pressure washdowns (CIP/SIP cycles).
-
Maintenance-Free Operation: With no mechanically moving parts, there is no risk of wear or mechanical failure. The vibronic principle is immune to the effects of external vibrations and heavy foam.
-
Versatile Hygienic Connections: The device supports a wide variety of aseptic connections, including Tri-Clamp, Dairy Coupling, Varivent, and SMS, allowing for seamless integration into existing sanitary piping and vessels.
