The SICK LFP Cubic Series Level Sensor is a level sensor for liquids using TDR technology to determine the time of flight of electromagnetic waves. The time difference between the sent pulse and the reflected pulse generates a level signal. This sensor family can emit these signals continuously via analog output, and switching output. The LFP Cubic Series is
compatible with virtually any liquid. The modular probe allows for quick and easy integration. Deposit-forming and foaming liquids are not an obstacle. The sensor’s user-friendly setup uses four pushbuttons and a display to ensure quick and easy adaptation to the application. Additional features available include a remote amplifier, IO-Link interface, and a process connection variant in titanium maximize versatility.

Applications

  • Coolant and lubricant levels in machine tooling
  • Cleanser and detergent levels in cleaning and washing machines
  • Filling tanks in automobile assembly
