Level sensors
LFP Cubic

Flexible up to the probe tip

Your Benefits

  • Rugged design increases service life
  • High flexibility with interchangeable rod probe or cable probe that can be cut to length
  • Cost savings due to multiple output signals: One system for both point level and continuous level measurement
  • Maintenance-free and easy to commission without calibration, saving time and money
  • Titanium process connection is highly resistant to chemicals
  • Compact, rotatable housing and remote amplifier for flexible installation
  • High availability, even when several sensors are installed in parallel, since there is no mutual device interference
  • Universal technology facilitating calibration-free measurement saves time and money


Flexible up to the probe tip

The LFP Cubic is a level sensor for liquids using TDR technology – a process for determining the time of flight of electromagnetic waves. The time difference between the sent pulse and the reflected pulse is used to generate a level signal. The sensor can emit this a as continuous measured value (analog output) and a freely positionable switching point (switching output). The LFP Cubic is compatible for use in virtually any liquid. Thanks to its modular probe, the sensor can be integrated quickly into any application. It can even be used in deposit-forming and foaming liquids. The sensor’s intuitive setup uses four pushbuttons and a display to ensure quick and easy adaptation to the application. Remote amplifier, IO-Link interface, and a design which features a process connection in titanium are additional features for versatile use.
