General

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 design with stainless steel housing.

• Process connections: Threads
• Temperature: -40 to +150°C (-40 to +302°F)
• Pressure: -1 to +40bar (-14.5 to 580psi)
• Surface roughness: 3.2µm
• Overfill protection and leakage detection WHG, marine approvals, final inspection report

Features

• 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
