Field of application
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 protection or pump dry-run protection in cleaning systems. The IO-Link capability allows easy parameter setting.Compact:- Smallest vibronic sensor in the marketSafe:- Continuous self-monitoring-Reliable switching independent of media propertiesEasy:- No calibration – Plug & play- IO-Link connectivity
Point level switch in compact design with stainless steel housing.Process connections: ThreadsTemperature: -40 to +150°C (-40 to +302°F)Pressure: -1 to +40bar (-14.5 to 580psi)Surface roughness: 3.2µmOverfill protection and leakage detection WHG, marine approvals, final inspection report
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. IO-Link reduces costs and complexity due to easy configuration of the devices via engineering toolsA 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 bubblesNo calibration is required, no specific know-how or tools (e.g. software) necessaryRobust design made of stainless steel (316L) assures highest durabilityA modular design offers different process temperatures and the widest variety of process connections and accessories in the market to fit every applicationNo mechanically moved parts, free of maintenance
