Liquipoint FTW23
Capacitance point level measurement
Point level switch for liquids
in the food and beverage industry
The Liquipoint FTW23 is a point level switch for water-based liquids.
It is used preferably in storage tanks, mixing vessels and pipes. Developed and built
for the food and beverage industry, the Liquipoint FTW23 meets international
hygienic requirements.
The Liquipoint FTW23 can be used permanently in process temperatures up to
100 °C (212 °F) and in cleaning and sterilization processes to 135 °C (275 °F) for 60
minutes.
• Individual adjustment to each medium not necessary
• Easy installation thanks to compact design - even in tight conditions or where
access is restricted
• Robust stainless steel housing, optionally available with M12x1 connector with
IP69K protection
• Onsite function check via LED indication
• Function test of the switch output with test magnet
• Can be cleaned and sterilized in place (CIP/SIP)
• 3-A and EHEDG certificates
• Meets the requirements of EU 1935/2004, 10/2011, 2023/2006 and FDA 21
