2 .7 Fulfilling NAMUR recommendations
VEGABAR 74 fulfills the following NAMUR recommendations:
l
NE 21 ( interference resistane and emitted interference)
l
NE 43 ( signal level for failure information)
l
NE 53 ( compatibility sensor and indicating/adjustment
components)
VEGA instruments are generally upward and downward
compatible:
l
S
ensor software to DTM VEGABAR 74 HART
l
DTM VEGABAR 74 for adjustment software PACTware™
T he parameter adjustment of the basic sensor functions is
independent of the software version. The range of available
functions depends on the respective software version of the
individual components.
T
he software version of VEGABAR 74 HART can be read out
via PACTware™.
