Application / Function
Application The Liquiphant T FTL260 is a reliable point level switch for liquids. It can be used in tanks and pipes as pump protection and as an alternative to float switches in storage vessels. The FTL260 is unaffected by build-up, turbulence and gases 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. The FTL260 can be directly connected to miniature contactors, solenoid valves or to a PLC.
