The Liquiphant FTL 260 is a compact limit switch, to which miniature contactors , magnetic valves and programmable logic controllers (PLC) can be directly connected.
Function and Dimensions:
The symmetrical vibrating fork is excited to its resonant frequency which changes when the fork is submerged in liquid.
The change is registered by the electronics, which actuate an electronic switch.
The Liquiphant FTL 260 can be operated in both minimum or maximum fail-safe mode, i.e. the electronic switch opens on reaching the limit value, in cases of fault or a loss of power.
