E+H FTL51B Vibrating Fork Point Level Switch

The Liquiphant FTL51B is E+H's new-generation vibrating fork point level switch for liquids, featuring an extension pipe. It is designed for high and low-level detection in tanks, vessels, and pipelines, providing overfill prevention and pump dry-run protection. It supports explosion-proof standards and SIL safety loops, making it widely applicable in industrial processes such as chemical and pharmaceutical manufacturing.

• Meets SIL2/SIL3 functional safety requirements; supports guided self-tests for SIL and WHG compliance with automatic generation of verification documentation.
• Equipped with Heartbeat Technology for continuous device self-diagnostics, enabling predictive maintenance.
• Supports digital communication (Bluetooth, HART, etc.); allows for convenient commissioning and device information access via the SmartBlue App.
• Measurement remains stable and unaffected by bubbles, foam, turbulence, medium buildup, or equipment vibration.
• Offers various process connections and comprehensive certifications (explosion-proof, marine, hygienic, etc.) to suit complex operating conditions.
• Plug-and-play operation requiring no calibration; available with extension pipes up to 6m in length to accommodate various installation depths.
