Details

The Endress+Hauser FTL825 Nivotester supplies the Liquiphant FailSafe FTL8x level switch with DC voltage via a 2-wire cable. At the same time it checks the current values (4 - 20 mA discretely) of the Liquiphant and sends a switching signal. The signal inputs of the Nivotester FTL825 are galvanically isolated from the mains and the outputs and can be ordered for safety-critical systems with up to SIL3. For industries in which redundant or diverse systems are not useful or possible.
