Field of application
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 protection 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
Point level switch in compact hygienic design with stainless steel housing for the food industry.
Process connections: Threads, hygienic process connections, M24 process adapter
Temperature: -40 to +150°C (-40 to +302°F)
Pressure: -1 to +40bar (-14.5 to +580psi)
Surface roughness: 0.76µm or 1.5µm
Overfill protection and leakage detection WHG, hygienic certificates, final inspection report
Benefits
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
