Sick LFP Inox Level Sensor

Sick LFP Inox Level Sensor

The Sick lFP Inox is a hygienic level sensor for liquids and uses TDR technology (time domain reflectrometry) for continuous level measurement.

The use of robust FDA-compliant materials like stainless steel in an EHEDG certified design means that the LFP Inox guarantees optimal, unrestricted cleaning, even for the highest hygiene requirements.

The LFP Inox sensor has a modular connection system which allows for simple and flexible installation in any application. The LFP Inox level sensor also has high temperature and pressure resistance which allows for unrestricted use in CIP and SIP conditions.

Sick LFP Inox Level Sensor - Features & Benefits

  • Level monitoring in hygienic applications
  • Manually cutable monoprobe made from stainless steel 1.4404 up to 2,000mm long with Ra ≤ 0.8µm
  • Process temperature up to 150 °C, process pressure up to 16 bar
  • CIP/SIP resistant
  • IP 67 and IP 69K enclosure rating
  • Interchangeable hygienic process connections
  • 3-in-1: combined display, analog output and binary output
  • Analog output 4mA to 20mA / 0V to 10V, switchable, plus two binary outputs
  • Robust design increases service life
  • High flexibility due to cutable probe and interchangeable connection concept
  • Cost savings due to multiple output signals: one system for both level detection and continuous level monitoring
  • Time and cost savings due to low maintenance and quick commissioning
  • No calibration or recalibration required for commissioning, thus saving time and costs
