LFFS

๐Ÿงช What This Data Means โ€” For Quick Client Selection

โœ” Universal liquid compatibility

LFFS works with water, oils, solvents, viscous media, and acidic/alkaline chemicals โ€” enabling one sensor type across multiple processes.

โœ” Hygienic & CIP/SIP ready

High-temperature resistance (up to 150 ยฐC in SIP) makes it suitable for food, dairy, and pharma processing lines.

โœ” IO-Link for smart control

Provides digital parameterization, real-time detection status, fluid type recognition, and predictive diagnostics.

โœ” Reliable in harsh media

Because the sensor has no vibrating forks or floats, it works even in coating, foamy, sticky, or aerated liquids.

โœ” Fast switching for automation

With <100 ms reaction time, it fits applications like filling machines, bottling lines, dosing skids, and pump control.

โœ” High pressure & robust design

Up to 40 bar operation allows safe use in chemical reactors, pressurized vessels, and industrial pump lines.

โœ” Install anywhere

Horizontal side-mounting, vertical pipe installation, or tank-top mounting โ€” flexible for OEM & retrofit use.

โœ” Ideal for applications such as:

  • Dairy, food & sanitary process tanks

  • Pharmaceutical reactors & mixing tanks

  • Chemical storage tanks & dosing lines

  • CIP return detection

  • Pump dry-run protection

  • Water treatment and wastewater systems
