Sick LFP Cubic Level Sensor

Sick LFP Cubic Level Sensor

The Sick LFP Cubic level sensor uses TDR technology (time domain reflectometry) and thus can be used in oil and water based liquids without calibration. 

The Sick LFP Cubic's guided radar uses time of flight technology to measure electromagenetic pulses and has a flexible probe that can be changed or cut allowing the sensor to be quickly integrated into any applications. The LFP Cubic sensor can also be used in deposit-forming and foaming liquids.

The LFP sensor's intuitive setup uses four buttons and a display to ensure quick and easy adaptation to the application. Additionally the sensor has discrete and analog output signals, an IO-Link interface is available to transmit additional valuable process data to the control unit.

Sick LFP Cubic Level Sensor - Features & Benefits

  • No mechanical moving parts
  • Manually cutable and exchangeable monoprobe with lengths from 200mm up to 2,000mm
  • Immune to deposit formation
  • Process temperature up to 100ºC; process pressure up to 10 bar
  • Small inactive areas, ideal for small containers
  • Accurate measurement, even when liquid type changes
  • 3 in 1: Combined display, analog output (acc. NAMUR NE 43) and binary output
  • High enclosure rating if IP67 rotatable housing
  • Rugged design increases service life
  • High flexibility due to cutable and exchangeable monoprobe
  • Cost savings due to multiple output signals: one system for both level detection and continuous level monitoring
  • Time & Cost savings due to low maintenance and quick commissioning
  • No calibration or recalibration required for commissioning, thus saving time and costs
  • Compact and rotable housing ensures flexible installation
  • No crosstalk when several sensors are mounted next to each other
  • Advanced technology enables adjustment-free measurement of oil and water based liquids
