Safety instructions

2013-06-15 Design and specifications subject to change without notice

This instrument is constructed and tested according to the current EU-

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 connecting diagrams.

Before switching on the power supply take care that other equipment

is not affected. Ensure that the supply voltage and the conditions in the

environment comply with the specification 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

with a compliant cable.

Description

The Level Switch LBFS designed to detect levels in tanks, media separation and provide empty-pipe detection or dry-run protection

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 of 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.

WARNING

This product contains no replaceable parts. In case of malfunction the product must be shipped to Baumer for repair.

Operators instructions CleverLevel switch, LBFS Measuring principle The capacity (C) of the media is directly proportional to the dielectric value of the media A frequency between 100 and 180MHz is swept into the media When the coil (L) and the capacitor (C) reach a resonance frequency, it will be detected by the electrical circuit Mounting The thread must be sealed e.g. by a gasket, an O-ring or Teflon® tape and tightened into the counterpart.
