New Fieldbus Options for Level meters

  • FOUNDATION Fieldbus and PROFIBUS PA available for OPTIWAVE 5200 C and OPTIFLEX 2200 C level meters


OPTIWAVE 5200 C and OPTIFLEX 2200 C level meters now available with FOUNDATION Fieldbus and PROFIBUS PA

OPTIFLEX 2200 C and OPTIWAVE 5200 C level meters are now available with 2-wire bus protocols FOUNDATION Fieldbus and PROFIBUS PA. For each protocol, a dedicated PACTware DTM enables to access the device parameters directly via the instrument.

Bus protocols for OPTIFLEX 2200 C TDR guided radar and OPTIWAVE 5200 C FMCW radar level meters meet the latest PROFIBUS PA Profile V3.02 and FOUNDATION Fieldbus ITK 6.1 interoperability testing. Furthermore, KROHNE is engaged in additional interoperability tests by Bilfinger Maintenance Süd GmbH, Germany, (formerly known as BIS) - a Fieldbus Foundation Center of Excellence and PROFIBUS PI Competence Center (PICC).

The PROFIBUS PA versions provide function blocks for level, distance, ullage conversion and volume conversion. The FOUNDATION Fieldbus protocol additionally supports LAS (Link Active Scheduler) functionality that permits to use the level meters as master within an FF topology. Both versions are meeting FISCO safety model for ATEX/IECEx zone 0, 1 and 2 (Ex i as well as Ex d).

OPTIFLEX 2200 C/F and OPTIWAVE 5200 C/F are designed for the chemical, petrochemical, power, pulp and paper industries and comply with all applicable NAMUR standards (NE 21, 43, 107 and 53). Both level meters are approved for use in ATEX, IECEx, cFMus and NEPSI for intrinsically safe as well as in explosion proof areas. Compact versions with analogue output meet SIL2 requirements according to IEC 61508.
