The science (or even the art ) of instrumentation is of fundamental
import ance to engineers, scientists and medical workers.
Instruments are the eyes and ears of the technologist. (His nose is
reserved for detecting the effects of excess current. ) Without
sensors and their associated signal processing systems there would
be no modern transport, no National Grid distributing electricity,
and anyone unlucky enough to fall ill would be offered only the
most primitive medical treatment. The progress that has been made
in almost all areas of technology can be seen in terms of the rate
at which the necessary instrumentation has been developed. For
example, in recent years many improvements have been made to the
performance of the internal combus tion engine. More and more power
has been squeezed out of smaller and more economic engines. One of
the reasons is that in the last few years sensors have been
developed which allow investigations to be made of the way in which
the flame front spreads inside a cylinder after ignition. This work
has led to a redesign of the geometry of the inlet valves and the
piston, and more efficient engines are the result. The process of
instrumentation is often considered solely in terms of the sensors
used and their associated electronics. However, there are two steps
involved in making any measurement. These are, first, getting the
data, which is where sensors and electronics are used, and second,
analysing it."
