Description
The Level Switch LFFS designed to detect levels in tanks, media separation and provide empty-pipe detection or dry-run protection
for pumps.
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.
