A. Product Overview

Baumer CleverLevel LFFS is a universal point level switch used for detecting the presence or absence of media in tanks, vessels and pipelines. It is suitable for liquids, solids, sticky media and viscous products with a dielectric value above 1.5.

The LFFS can be used for applications such as tank level detection, media separation, empty pipe detection and dry-run protection for pumps. It supports configurable output options such as PNP, NPN and digital output through the FlexProgrammer 9701.

The sensor is designed to work reliably even in difficult process conditions. It can be adjusted for foam, bubbles, condensate and viscous media through Flex software. This makes it useful for applications where ordinary level switches may give false signals due to coating, sticky residue or changing media conditions.

Baumer CleverLevel LFFS is also suitable for hygienic installations with proper Baumer accessories. It is resistant to CIP and SIP cleaning agents, making it suitable for food, beverage, pharmaceutical and clean process industries.

B. Working Principle

The Baumer CleverLevel LFFS works on a capacitive frequency sweep measuring principle.

Inside the sensor tip, an electrode forms a capacitor with the surrounding environment. When the media comes near or touches the sensor tip, the dielectric value of the media changes the capacitance. This capacitance change affects the resonance frequency inside the sensor.

The sensor compares the measured resonance frequency with the programmed switching threshold. Based on this, it gives a switching output to the PLC, controller, relay or automation system.

The sensor can be configured through FlexProgrammer 9701 for output type, damping, diagnostics, Teach-In and application-specific settings. Teach-In allows the sensor to learn empty and full conditions for better accuracy in the actual process.

C. Why It Is Used

Baumer CleverLevel LFFS is used when reliable point level detection is required in demanding applications. It helps prevent overflow, dry running of pumps, incorrect filling, empty pipe operation and process interruptions.

It is especially useful where the media is sticky, foamy, viscous or difficult to detect. Products such as water, beer, honey, yoghurt, toothpaste, ketchup, sugar and flour can be detected using this sensor.

The LFFS is also used because it is not highly affected by mounting position inside the tank. With correct installation and configuration, it provides stable switching even when the media level fluctuates during filling or emptying.

Its high temperature capability, hygienic process connection options, configurable output and resistance to CIP and SIP cleaning make it a reliable choice for industrial and hygienic process applications.

FAQ

1. What is Baumer CleverLevel LFFS used for?
   Baumer CleverLevel LFFS is used for point level detection in tanks, vessels and pipes. It can detect liquids, viscous media, sticky products and dry bulk materials. It is also used for media separation, empty pipe detection and pump dry-run protection.
2. Is Baumer LFFS suitable for high temperature applications?
   Yes. Baumer CleverLevel LFFS is suitable for high temperature applications when selected and installed with the correct version and mounting connection. Sliding connection versions can be used in high media temperature applications as per installation conditions.
3. Which media can Baumer LFFS detect?
   Baumer LFFS can detect liquids such as water and beer, viscous and sticky products such as honey, yoghurt, toothpaste and ketchup, and dry media such as sugar and flour.
4. What output options are available in Baumer CleverLevel LFFS?
   Baumer CleverLevel LFFS can be configured for PNP, NPN or digital output using the FlexProgrammer 9701.
5. Can Baumer LFFS be used in hygienic applications?
   Yes. Baumer LFFS can be used in hygienic applications when installed with suitable Baumer hygienic mounting accessories. It is also resistant to CIP and SIP cleaning agents.
6. Does Baumer LFFS work with foamy or sticky media?
   Yes. Through Flex software, compensation can be set for foam, bubbles, condensate and viscous media. This helps reduce false switching in difficult applications.
7. What is the measuring principle of Baumer CleverLevel LFFS?
   Baumer LFFS uses a capacitive frequency sweep measuring principle. The media changes the capacitance near the sensor tip, which changes the resonance frequency. The sensor then switches according to the programmed threshold.
8. Can the sensor be adjusted on site?
   Yes. The sensor can be adjusted through Teach-In or configured using FlexProgrammer 9701 and Flex software. Empty and full conditions can be taught for better application-specific performance.
9. Is Baumer LFFS suitable for pump dry-run protection?
   Yes. Baumer LFFS can be used for empty pipe detection and dry-run protection of pumps. It helps protect pumps from running without media.
10. Who should buy Baumer CleverLevel LFFS?
    Baumer CleverLevel LFFS is suitable for food and beverage plants, pharmaceutical companies, chemical industries, OEMs, system integrators, maintenance teams and automation users who need reliable point level switching in tanks, vessels and pipelines.
