directives and packed in technically safe condition. In order to maintain
this condition and to ensure safe operation, the user must follow the
instructions and warnings given in this instruction.
During the installation local standards have to be observed. Ignoring the
warnings may lead to severe personal injury or substantial damage to
property.
The product must be operated by trained staff. Correct and safe opera-
tion of this equipment is dependent on proper transport, storage, instal-
lation and operation.
All electrical wiring must conform to local standards and the connection
must be made according to the connection diagrams.
Before switching on the power supply make sure that other equipment
is not affected. Ensure that the supply voltage and the conditions in the
environment comply with the specifications of the device.
Before switching off the supply voltage check the possible effects on
other equipment and the processing system.
To obtain the specified protection degree, the LBFS must be mounted

Description
The Level Switch LBFS is designed to detect levels in tanks, media separation and provide empty-pipe detection or dry-run protec-
tion for pumps.
A high frequency sweep signal is radiated from the sensor tip into the tank. The media will act as a virtual capacitor, which together
with a coil in the sensor head, will form a circuit creating the switch point signal. This virtual capacitance will depend on the di-
electric value of the media.
Two output signals are available, Normally Open (NO) and Normally Closed (NC). By means of the FlexProgrammer 9701, a
damping of the output signal can be activated in case of a fluctuating media level, e.g. during tank filling. Additionally the output
signals NO and NC can be reversed.
The measurement is precise and unaffected by the mounting position in the tank. In the Flex-software a compensation for foam,
bubbles and condensate as well as sticky media can be set.
The Flex-software also features an adjustment facility making the user able to adjust the sensor to a specific media.
The Level Switch LBFS measures liquids such as water and oil. Even dry medias can be measured, eg. coal dust or plastic granu-
late.
Level Switch LBFS can be delivered with PNP output as well as NPN output.
The process connection can easily be sealed by use of Teflon Tape or by use of special welding adapter for the hygienic edition.
