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 protection WHG, SIL, marine approvals

Use in safety systems requiring functional safety to SIL3 in accordance with DIN EN IEC 61508 Ed.2.0 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

Vibronic measuring principle

Functional safety SIL in process instrumentation

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