Tutorial 1 – Introduction of CM
Q1.
Describe what is meant by (a) Instrumentation, and (b) Condition Monitoring.
(a) Instrumentation
Instrumentation for measuring instruments that are used for indicating, measuring and
recording physical quantities. Such as sensor, signal conditioning,signal
processing,communication and also action for data handling , data,manipulation,
display & visualization and making decision
Q2.
What is meant by the term asset management?
Asset management to counter the negative impact. This is achieved by systematic
condition monitoring of equipment to avoid unplanned production downtime and to
reduce operational expenses by optimizing maintenance planning.
Q3.
Explain the difference between on-line and off-line condition monitoring and give a
specific practical example of each type.
On-line CM Off-line CM
Plant item or equipment is in service Plant item or equipment is in out of
while monitoring happens. service while monitoring happens or in
specific state for monitoring.
Plant item or equipment is undergoing Often, normal intervention is required.

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.
