Level sensor LFP cubic TDR– Sick

LFP Cubic – Flexible up to the probe tip!

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

The LFP’s guided radar uses time-offlight technology to measure electromagnetic pulses. The time difference between the sent pulse and the reflected pulse is used to calculate the level, both as a continuous value (analog output) and a freely position able switching point (switching output). Due to its flexible probe that can be changed or cut, it is possible to integrate the sensor quickly into any application. The LFP Cubic can work in deposit-forming and foaming liquids. The sensor’s intuitive setup uses four buttons and a display to ensure quick and easy adaptation to the application. 
In addition to the discrete and analog output signals, an IO-Link interface is available to transmit additional valuable process data to the control unit.
