Field of application

Liquiphant FTL80 is a point level switch for use in hazardous areas with all international certificates. FailSafe overfill protection in applications with functional safety up to SIL3 with one device. Reliable measurement values, not affected by: changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.

Point level switch for liquids up to SIL3.

Process connections: Threads and flanges
Temperature: -60 to +280°C (-76 to +540°F)
Pressure: -1 to +100bar (-14.5 to +1,450psi)
Sensor material: 316L, Alloy C
International explosion protection certificates, overfill protection WHG, SIL, marine approvals

Benefits

Use in safety systems requiring functional safety to SIL3 in accordance with IEC 61508 Ed.2.0/ IEC 61511-1/ISA 84-1 and DIN EN ISO 13849
Proof test: proof testing interval up to 12 years, Slave devices tested at the press of a button
Permanent self-monitoring/internal redundancy
4-20mA interface (acc. to NAMUR NE 06/NE 43): easy integration via the switching unit (Nivotester FailSafe FTL825) with a two-channel output (safety contacts) and locking function or direct integration into a safety PLC
No adjustment: quick, low-cost startup
No mechanically moving parts: no maintenance, no wear, long operating life
Monitoring of fork for damage, corrosion, build-up and mechanical blocking
