LFP Inox and Cubic: Intelligent sensors for level and point level measurement

SICK offers solutions for a wide range of level and point level
measurement applications with its LFP Inox and LFP Cubic level sensors. The
sensor options feature differing probe lengths and probe types, and therefore
cover fields of application in the food, beverage and pharmaceutical
industries, permitting realisation of highly efficient processes.

LFP Cubic and LFP Inox sensors operate according to the TDR (time domain
reflectometry) measurement principle. This ‘guided microwave’ principle
determines the propagation times of electromagnetic waves. A level signal is
generated from the time difference between the transmitted and reflected
pulses. The sensor can output this signal as a continuously measured value
(analogue value) and can additionally derive freely positionable switching
points from the signal (switching output).

The procedure ensures maximum reliability and the best possible
measurement results. Factors such as pressure, temperature, vacuum or dust have
no significant impact. The specially developed foam mode allows LFP sensors to be
also used for highly foaming media.

LFP Cubic – Flexible
up to the probe tip

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.
The sensor 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 measuring task. Separate electronics, IO-Link
interface, and a design which features a process connection in titanium, allow versatile

LFP Inox – The clean

The LFP Inox is a hygienic level sensor for liquids. The use of
FDA-compliant materials in an EHEDG-certified design means that the LFP Inox
can be relied upon for optimum and unrestricted cleaning – even in applications
with the most stringent hygiene requirements. Its modular connection system
allows simple and flexible installation in any application. Thanks to high
temperature and pressure resistance, unrestricted use is possible under CIP and
SIP conditions. This impressive profile is topped off with communication
capability via IO-Link to the superordinate control units.
