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
