Endress + Hauser Vibronic Point level detection Liquiphant FTL70

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.

Benefits

Use in safety systems requiring functional safety to SIL2 in accordance with

IEC 61508/IEC 61511-1

With welded gas tight feedthrough maximum safety in the event of damaged sensor

Wide variety of electronics, e.g. NAMUR, relay, thyristor, PFM signal output: the right connection for every process control system

Large number of process connections to choose from: universal usage

No calibration: quick, low-cost start-up

No mechanically moving parts: no maintenance, no wear, long operating life.

Monitoring of fork for damage: guaranteed function

FDA approved materials (PFA Edlon)
