Description

Application

The Liquiphant FTL31 is a compact point level switch specifically designed for liquid detection across various industrial sectors, particularly the machinery industry. It is ideal for applications such as overfill prevention and dry-run protection in cleaning systems. Its IO-Link capability enables seamless parameterization.

Key Features:

  • Compact: The smallest vibronic sensor available.
  • Safe: Continuous self-diagnosis and dependable switching, irrespective of the liquid's properties.
  • Easy: No need for calibration; plug & play with IO-Link connectivity.

The Liquiphant FTL31 is a compact solution encased in durable stainless steel.

  • Process connections: Threaded connections.
  • Operating temperature: -40 to +150°C (-40 to +302°F).
  • Pressure range: -1 to +40 bar (-14.5 to 580 psi).
  • Surface finish: 3.2 µm.
  • Certifications: Overfill protection, leakage detection (WHG), marine approvals, and final inspection reports.

 


Benefits

The Liquiphant FTL31 is engineered to meet the highest standards of quality and environmental responsibility. It ensures safe operation, even in the event of power loss, by providing continuous self-monitoring and accurate switching, regardless of changes in the media's properties.

With IO-Link functionality, device configuration is simplified, reducing both costs and operational complexity. Its true plug-and-play design requires no adjustments, even when media properties vary. The sensor is unaffected by factors such as conductivity, build-up, turbulence, flow, or air bubbles.

  • No calibration needed: No special expertise or tools required.
  • Robust construction: Made from stainless steel (316L) for superior durability.
  • Modular design: Supports a wide range of process temperatures, connections, and accessories, ensuring compatibility with virtually any application.
  • Maintenance-free: With no moving mechanical parts, it requires no regular upkeep.
