The Nivotester FTL825 directly powers the Liquiphant fail-safe FTL8x vibronic level switch via a two-core cable, while analyzing the Liquiphant current value (independent 4-20 mA) and returning the switch signal. The input signal of the Nivotester FTL825 is electrically isolated from the output and the power supply; the system functional safety reaches SIL3, and redundant or diverse systems are not recommended or cannot be used.
Benefits
SIL3 functional safety features: internal dual-channel design, permanent self-monitoring, online monitoring of the connection to the sensor, permanent monitoring of the Liquiphant fail-safe limit switch
LIVE signal permanently visualized
Advanced fault detection functions and error message display
Verification of the entire measuring system, including the control and signaling devices in the loop, via the verification test key or remote control
Integrated locking function (self-holding)
Four switch outputs (individually evaluable): two as level safety contacts in accordance with the quiescent-current principle for output signal redundancy; one signal contact (e.g. lamp), one fault-signal changeover contact
Proof test: proof test intervals of up to 12 years
Applications
Fail-safe limit detection switch, rail-mountable
Ambient temperature: -20 ~ +60°C (-4 ~ +140°F)
International explosion-protection approval, overflow protection WHG
