Chemical Industry KEYENCE Level Sensor Anti Interference Non Contact
High Precision Anti-Interference Non-Contact Level Sensor for Chemical & Food Industry
Level Sensor - High Precision Non-Contact Detection
Level Sensor delivers high-precision non-contact liquid level detection with strong anti-interference performance, ideal for chemical processing and food production. It maintains stable measurement accuracy even in harsh environments with foam, vapor, turbulence, or corrosive media, eliminating false alarms and ensuring consistent process control. The non-contact design prevents contamination and wear, supporting hygienic standards in food and beverage applications while extending service life in chemical tanks.
Key Features & Benefits
  • High Precision & Anti-Interference: Guided pulse/radar technology delivers ±0.1%FS accuracy, immune to foam, vapor, turbulence, and build-up
  • Non-Contact & Wear-Free: Prevents contamination and wear, ideal for hygienic food and corrosive chemical applications
  • Wide Media Compatibility: Works with water, oil, chemicals, and viscous liquids; withstands high temperature, pressure, and corrosion with IP67/68 protection
  • Easy Setup & Smart Output: One-click calibration with no frequent recalibration; supports 4-20mA, IO-Link, NPN/PNP for easy automation integration
  • Long Range & Hygienic Design: 0-20m measurement range; crevice-free design for food/pharma CIP/SIP and remote tank monitoring

Frequently Asked Questions
Can it measure liquids with foam or bubbles?
Yes. KEYENCE level sensors use guided-wave/radar technology that penetrates foam, vapor, and bubbles without false triggering, ensuring stable readings even with heavy foam.
Can it be used with corrosive chemicals?
Most models use PTFE or corrosion-resistant materials for wetted parts, suitable for acids, alkalis, solvents, and other corrosive liquids. Confirm material compatibility with your specific media.
Is it suitable for food/hygienic applications?
Yes. Hygienic/sanitary versions are available, crevice-free and easy to clean, compliant with food and pharmaceutical standards for tanks, dosing, and CIP/SIP processes.
How accurate is it?
Typically ±0.1% FS with resolution down to 1 mm. Stable even in high-temperature, high-pressure, or turbulent conditions.
Do I need to calibrate it often?
No. Most models only require one-time setup/calibration and remain stable long-term without frequent recalibration.
