Information
Coated point level switch for liquids for FailSafe overfill protection
Point level switch for liquids up to SIL3.
Process connections: Threads and flanges
Temperature: -50 to +150°C (-76 to +300°F)
Pressure: -1 to +40bar (-14.5 to +580psi)
Sensor length: Extension pipe up to 3m (9.8ft)
Sensor material: Enamel, ECTFE and various PFA materials
International explosion protection certificates, overfill protection WHG, SIL
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, buildup 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
