Vibronic measuring principle

Liquiphant with permanent function check is the safe choice for point level detection in liquids

Point level switch for liquids in 
high-temperature applications

Liquiphant FT70 is a point level switch for use in hazardous areas with all international certificates. FTL70 is especially designed for applications with high process temperatures up to 280°C and can be used for Safety Instrumented Systems up to SIL2, in homogeneous redundancy up to SIL3. An integrated second line of defense offers the highest degree of safety. Reliable measurement values, not affected by: changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.
