E&H Liquiphant FTL33 Vibronic Point level detection

Liquiphant FTL33 is a point level switch for liquids. The FTL33 is especially designed for food & beverage applications where hygienic requirements are requested. The Liquiphant is used for overfill prevention or pump dry-run protection. The IO-Link capability allows easy parameter setting.
Compact:
– Smallest vibronic sensor in the market
Safe:
– Continuous self-monitoring
– Reliable switching independent of media properties
Easy:
– No calibration
– Plug & play
-IO-Link connectivity

  • Designed for hygienic applications especially in the food industry – hygienic process connections and approvals available. IO-Link reduces costs and complexity due to easy configuration of the devices via engineering tools
  • CIP and SIP cleanability ensured – up to protection class IP69k
  • 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 – no mechanically moved parts, free of maintenance

Point level switch in compact hygienic design with stainless steel housing for the food industry.
