Application
The Liquiphant FTL33 is a point level switch for universal use in all liquids. It is used preferably in storage tanks, mixing vessels and pipes, where the internal and external hygiene requirements are particularly stringent. The reliable switching function works independently from product characteristics such as conductivity and dielectric constant value.
Function
A piezoelectric drive causes the tuning fork of the Liquiphant FTL33 to vibrate at its resonance frequency. When the tuning fork is immersed in a liquid, its intrinsic frequency changes due to the change in density of the surrounding medium. The electronics system in the point level switch monitors the resonance frequency and indicates whether the tuning fork is vibrating in air or is covered by liquid. A signal is output via the DC-PNP, AC/DC or IO-Link electrical connection.
Application Example
The point level switch can be installed in any position in a vessel, pipe or tank, e.g., as overfill prevention or upper level detection (1), lower level detection (2) or dry running protection for pump (3)

IO-Link
Besides its general benefits, summarized below, using IO-Link point-to-point communication with our hygienic level switch
Liquiphant FTL33 allows:- Adjustment to densities less than 700 g/l
- Media diffeentiation between two media (e.g. interface detection)
- Second switch output (parallel switching)
General benefits of IO-Link
Digital measured values:
• Faultless transmission (e.g. EMC caused)
• No conversion, thus a higher total accuracy
More data
• Possibility to carry more values
• Detailed fault information
• Additional process information
Central parameters storage
• Possibility to load set up parameters from the master into a device
• Configuration can be duplicated from one device to the next
• Remote sensor maintenance
