Vibronic Point level detection Nivotester FailSafe

E+H/Endress+Hauser

• Suitable for safety systems requiring functional safety up to SIL3 in accordance with IEC 61508 Ed.2.0 / IEC 61511-1 / ISA 84.1 • Proof test interval of up to 12 years; slave devices can be tested at the press of a button • Designed for safety-critical applications up to SIL3 in the chemical, petrochemical, and oil & gas industries • Ideal for applications where redundant or diverse systems are not recommended or feasible, extended test intervals are required, or proof testing is difficult and costly • Integrated locking function (self-holding) • Four independently analyzable switching outputs: • Two level safety contacts based on the de-energized-to-trip principle for redundant output signals • One signaling contact (e.g., for lamp indication) • One fault signaling contact with changeover function
