SICK LFC Capacitive Liquid Level Switch — Hygienic IO‑Link Level Monitoring

SICK LFC: Capacitive Liquid Level Switch for Hygienic Industries

The LFC is a compact, cost-effective point-level switch designed for reliable liquid monitoring.

It combines capacitive sensing with IO-Link intelligence for fast setup and remote configuration.

Key features & benefits

• Flexible plug-and-play: Factory preset for water-based media; supports oils, beer, CIP fluids.
• Hygienic design: Compliant with EG1935/2004 and FDA; supports CIP and SIP cleaning.
• Robust performance: Operating range -20°C to +100°C (supports 1h at +135°C), pressure -1 to +64 bar, protection IP66/IP67/IP69.
• Smart IO-Link: Dual digital outputs (PNP/NPN), real-time status reporting and remote parameter configuration.
• Reliable sensing: Detects liquid level while rejecting foam and buildup to avoid false triggers and reduce maintenance.

Applications & industries

Ideal for food & beverage, dairy, brewing, pharmaceutical and chemical facilities. Typical uses include:

• Tank and vessel point-level detection.
• Pipeline dry-run protection to prevent pump damage.
• Overflow protection and low-level alarms for storage tanks.
• CIP/SIP-compatible monitoring to lower cross-contamination risk.
