The
failure
rates
are
valid
for
the
useful life of the instrument. The circuits of the Level
Transmitter LB490 Uni-Probe evaluation unit do not contain
any
components
with
limited
useful
lifetime which are contributing to the dangerous
undetected
failure
rate.
For
typical
applications,
the
photomultiplier
tube
has a useful lifetime of more than 7,5 years with 60Co radiation source
and more than 21 years with 137Cs radiation
source.
When
plant
conditions
and
experience
indicate
a
shorter
useful
lifetime
than indicated in this appendix, the number based on plant
experience shall be used.
The PFD
AVG
was calculated for three different proof test intervals.

The boxes marked in green mean that

for
SIL

according to table 2 of IEC 61508-1 and table 3.1 of ANSI/ISA–84.01–1996 and
do
fulfill
the
requirement
to
not
claim
more
than 35% of this range, i.e. to be better than or equal
to 3,5E-03.
