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 LFFS must be mounted

with a compliant cable.

Description

The Level Switch LFFS 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 capacity will depend of the di-electric

value (DK-value) of the media.

By means of the FlexProgrammer 9701 the output can be configured to either NPN, PNP or digital output signal. A damping of the

output signal can be activated in case of a fluctuating media level, e.g. during tank filling.

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 viscous 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 LFFS measures liquids such as water and beer as well as viscous, sticky fluids, such as honey, yoghurt, tooth-

paste and ketchup. Even dry medias can be measured, e.g. sugar or flour.

The Level Switch LFFS is resistant against CIP and SIP agents.

Hygienic installation is also possible with the comprehensive range of accessories, see the overview at page 6.
