Vibronic Point level detection Liquiphant FTL31

Point level switch for liquids in compact design with stainless steel housing

Replace FTL20,FTL260


Liquiphant FTL31 is a point level switch for liquids. The FTL31 is designed for industrial applications in all industries, mainly the machinery industry. The Liquiphant is used for overfill prevention or pump dry-run protection in cleaning and filter systems as well as in cooling and lubrication vessels.
Compact:
- Smallest vibronic sensor in the market
Safe:
- Continuous self-monitoring
- Reliable switching independent of media properties
Easy:
- No calibration or adjustment
- Plug & play

Benefits

  • Designed according to highest requirements to quality and environmental sustainability. The self-monitoring Liquiphant offers safe switching
    also in case of power supply loss

  • Independent of changing media properties an accurate switching point is offered

  • A real plug & play sensor is offered without any need for adjustment even with changing media. Measurement is unaffected by conductivity,
    build-up, turbulence, flows or air bubbles

  • No calibration is required, no specific know-how or tools (e.g. software) necessary

  • Robust design made of stainless steel (316L) assures highest durability

  • A modular design offers different process temperatures and the widest variety of process connections and accessories in the market to fit
    every application

  • No mechanically moved parts, free of maintenance
