Baumer, CleverLevel LBFS/LFFS Switch


안녕하세요 TIATIP 입니다. 오늘 이 시간에는 바우머에서 새롭게 출시된 블록버스타급 레벨스위치 LBFS 그리고 LFFS Switch Series를 살펴보도록 하겠습니다.


With Baumer’s CleverLevel series, you can enter into a new era of level detection technology that is convenient, precise, easy and maintenance free.
CleverLevel – one product to meet all your detection needs!


The widely used vibration level switches have vibrating forks that are quite large and which protrude quite a ways into the material being


A high frequency sweep signal is radiated from the sensor tip into the media. The media will act as a virtual capacitor,  between the emitter in the sensor tip and the metal housing, which will form a circuit creating the switch point signal. This virtual capacitance will depend of the di-electric value of the media (DK value). 


Since pasty materials are prone to stick to these forks, it can often cause measuring errors. Coarse granular media such as grains can easily become lodged between the forks and also cause measuring errors. Moreover, not only are the forks difficult to clean, but liquid and powder substances even require different fork designs.

With the sensors of the CleverLevel switch, no media remnants or solids are able to accumulate on the sensors. A precise and reliable level detection is thus ensured even under difficult circumstances.

The perfect solution for your applications


※ Level detection for storage tanks, containers and pipelines
Storage, buffer and filling tanks are generally equipped with switches for detecting high and low filling levels. The sensor’s short response time facilitates precise and reliable level control.


※ Detection of different media and phase separation
In certain processes, the material appears in different phases. These can either be identified (e.g. oil on water) or their measurement might be masked (e.g. foam layer).


※ Detection of contaminants in media
Contamination of media is not only an issue for food production. Catching it early on in the process is economically advantageous. For example, remnants of cleaning agents can be reliably detected in liquid food products long before any subsequent processing takes place.


※ Protecting pumps from running dry
Pumps running dry is a critical process problem because it can lead to dosing deviations or damages. These challenges can be resolved even if the media is viscous or sticky.
