Detection Zone Coding for
More Efficient Condition
Monitoring
ese days, reliability
professionals are faced
with diverse options
related to technologies
and methods to detect, troubleshoot
and remediate problems. Figure
1 is a simple example of the avail-
able options to collect data and
arrive at decisions regarding the
health of machinery and machine
components. e logical starting
point is always to carefully rank
failure modes by both criticality
and probability of occurrence. For
more information on this topic,
see my previous column titled "A
New Look at Criticality Analysis
for Machinery Lubrication." is
method is known as failure modes
and effects analysis (FMEA), and
has been extensively documented.
e failure mode ranking sets
into motion the critical-path process
in reaching optimized decisions
related to condition monitoring
followed by the prescribed response
or remedy. is response should not
simply be corrective but also incorpo-
rate proactive measures to prevent or
restrict recurrence. e emphasis is
on optimized decisions and actions.
It's easy to go cheap (penny wise,
pound foolish), but there also can
be temptation at the other extreme
(a state of reliability excess), often
driven by fear of the unknown. e
optimum reference state is an activity
of seeking balanced decisions. After
"Condition
monitoring
is like a
treasure
hunt. e
greater fun
is in the
search."
