Field of application
Liquiphant FTL71 is a point level switch with extension tube for use in hazardous areas with all international certificates. FTL71 is especially designed for applications with high process temperatures up to 280°C and can be used 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 IECEndress+Hauser 61508/IEC 61511-1
* With welded gas-tight
feed-through maximum safety in the event of damaged sensor
feed-through 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
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
Monitoring of fork for damage: guaranteed function
* FDA approved materials (PFA Edlon)
