LFP Inox

The clean solution

Your Benefits

  • Rugged design increases service life
  • High flexibility – rod probe can be cut to length and connection concept is interchangeable
  • Cost savings as a result of 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
  • Remote display of measured values and saves space

Overview

The clean solution

The LFP Inox is a hygienic 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, both as a continuous value (analog output) and a freely positionable switching point (switching output). 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.
