Vibrating limit detection switch Liquiphant FTL20
Integrated limit detection switch, stainless steel housing
The Liquiphant FTL20 is an integrated limit detection switch. Typically used in tank areas, vessels and pipes, in cleaning and filtration systems and cooling and lubrication tanks for overfill protection or to prevent pump idling. The FTL20 is an ideal replacement for traditional pontoon switches, conductance, capacitance and optical sensors. Functional inspection can be performed by a magnet mounted on the outside. |
Advantage
