Basically Instrumentation deals with measurement and
indication/transmission of physical quantities, which are
used for control and monitoring of plants/equipment. When
the Control and monitoring part is performed without
intervention of human being , it is called automation. For
100% automation system take care of operation of
plant/machinery. But, still humen intervention is required
during start up, shutdown and abnormal condition since
practically 100% automation is not achievable over the
whole life cycle of automation.
