SIL 2/3 and FF/PA for OPTIWAVE radar level transmitters

KROHNE introduces SIL 2/3 certification and fieldbus communication options for the OPTIWAVE series.

The radar level transmitters have been designed according to IEC 61508 and are approved for use in safety-critical systems where a SIL 2/3 safety function (SIL 3 with 1oo2 channel architecture) is required. The SIL option is available for all 2-wire versions.
