Tutorial 1 – Introduction of CM
Q1. Describe what is meant by (a) Instrumentation, and (b) Condition Monitoring.
Instrumentation for measuring instruments that are used for indicating, measuring
and recording physical quantities. Such as sensor, signal conditioning, signal
processing, communication and action for data handling, data, manipulation,
display & visualization and making decision
Q2. What is meant by the term asset management?
Asset management is to offset the negative effects. This is done by systematic
condition tracking of equipment to prevent unplanned downtime in production and
by improving maintenance preparation to reduce operating expenses.
Q3. Explain the difference between on-line and off-line condition monitoring and give
a specific practical example of each type.
on-line CM
Plant item or equipment is in service while monitoring happens.
Plant item or equipment is undergoing normal operational behavior during
monitoring.
off-line CM
Plant item or equipment is in out of service while monitoring happens or in
specific state for monitoring.
Offline monitoring of circuit breakers.
, Q4. What are the different maintenance regimes that can be used in industry? Explain
the differences between them and list some benefits and disadvantages for each
one.
Maintenance Reactive Preventative Predictive
regime (Failure)
Benefit Repair on Maintain at fixed at Maintain on the
breakdown interval condition plant
Disadvantage Rate data is Costly and Costly
determining only ineffectively when Data can be
the average failure it is the sole type of misinterpreted,
rate the maintenance leading to false
practice maintenance
request
Q5. Which of the maintenance regimes in question 4 rely on condition monitoring?
Explain your answer.
Predictive maintenance because it can be monitor either offline or online.
Q6. It is not always advantageous to apply condition monitoring (CM). Explain why this
is the case and outline some of the conditions that are necessary for CM to be
effective.
Lack of historical data
May be costly
May be difficult to justify
Q7. What is (a) the best range, and (b) the best temperature resolution, you can identify
for a commercially available infrared thermography system? Please reference
your answer, for example a website.
Temperature: 0 – 40 degree Celsius
160x120
