Vibronic
Point level detection
Nivotester FailSafe FTL825
Point level switching unit for Liquiphant FailSafe FTL80, FTL81 and FTL85
Benefits
- Use in safety systems requiring functional safety to SIL3 in accordance with IEC 61508 Ed.2.0 /IEC 61511-1 / ISA 84-1
- Proof test: proof testing interval up to 12 years, Slave devices tested at the press of a button
- For safety-critical systems up to SIL3 in the chemicals, petrochemicals and oil & gas industries
- For applications where redundant or diverse systems are either not recommended or not possible, the longest possible test cycles are desirable, or proof tests are either not possible or only with great difficulty and expense
- Integrated locking function (self-holding)
- 4 switching outputs (can be analyzed separately): 2 as level safety contacts based on the quiescent current principle for a redundant output signal, 1 x signaling contact (e.g. lamp), 1 x fault-signaling contact as changeover contact
