Endress + Hauser Vibronic Point level detection Liquiphant FTL81

Point level switch for liquids for FailSafe overfill prevention

Liquiphant FTL81 is a point level switch for use in hazardous areas with all international certificates. 

FailSafe overfill prevention 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.

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

Mermanent 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

Field of application

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 length: Extension pipe up to 3m (9.8ft)

Sensor material: 316L, Alloy C

International explosion protection certificates, overfill prevention WHG, SIL, marine approvals
