E+H Liquiphant FTL80 Vibronic Point Level Switch

• 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
