Application / Function
Application Liquiphant T FTL20 is a reliable point level switch for liquids. Its 38 mm (1.5") fork and its small process connections enable mounting it also in tanks as in very narrow pipes for example as pump protection. The FTL20 is unaffected by build up, bubbles or turbulence and does not rely upon the electrical properties of the liquid.
ApplicationexampleFunction The integrated electronics detect the change in the fork’s vibrating frequency when they are covered and uncovered by the liquid. FTL20 can be directly connected to AS-i bus, alternating voltage or to a PLC.
