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 market Safe: – Continuous self-monitoring -Reliable switching independent of media properties Easy: – No calibration – Plug & play – IO-Link connectivity

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 tools

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
