Application
The Liquipoint FTW33 is a point level switch for liquid and pasty media. It is used preferably in storage tanks, mixing vessels and pipes. Developed and built for the food and beverage industry, the Liquipoint FTW33 meets international hygienic requirements. It is particularly suited to applications where flush-mounting is necessary. The Liquipoint FTW33 can be used permanently in process temperatures up to 100 °C (212 °F) and for 60 minutes in cleaning and sterilization processes up to 150 °C (302 °F). The Liquipoint FTW33 can also be used for detecting the foam that commonly occurs within the food and beverage industry.
Function
A low, galvanically isolated AC voltage is applied at the electrode in contact with the process. If liquid or pasty media come in contact with the
electrode, a measurable current flows and the Liquipoint FTW33 switches. Active buildup compensation ensures reliable switching of the measuring device even if buildup occurs on the sensor.Application Example
The measuring system consists of a Liquipoint FTW33 point level switch, e.g. for connection to programmable logic controllers (PLC).
a) Overfill protection or upper level detection (MAX)
b) Pump dry running protection (MIN)
c) Lower level detection (MIN)

IO-Link
Besides its general benefits, summarized below, using IO-Link point-to-point communication with our point level switch Liquipoint FTW33 allows:
- Adjustment on media with DC < 2
- Evaluation of thickness of buildup
- Two switching points adjustable for different media
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
