what are the diffrent applications of instrumentation?

Answer 1

Instrumentation can be used for operations or testing. Permanently installed sensors (for temperature, pressure, voltage or RPM, etc.) can be used by plant operators to control and log plant performance. Special test instrumentation may be installed to increase data acquisition or accuracy for plant acceptance tests or to calibrate operational instruments.

Answer 2

Instrumentation is used to measure physical events and trends. Things like temperature, pressure, fluid and gas flow, torque, speed (and rotational speed), are all measured using gauges.

Factory processes such as food manufacturing, chemical production, oil refining, etc. all use instrumentation to measure all the physical parameters. Things like how fast conveyer belts are moving, how hot the oven is (for baking), how much pressure is in that water line, are all measured by instruments. The results are sent back to a computer (called a PLC) where those measured quantities can be controlled (temperature too hot; turn down the heater -- conveyer belt too fast; slow down the motor).

Launch vehicles (rockets) and satellites need instrumentation to tell the ground controllers what is happening with the space vehicles (battery monitors, solar-cell charging current, temperature indicators, fuel bottle pressure indicators, sun or star sensors, etc.).

In laboratories, where new things are developed and invented, a lot of instrumentation is used to measure physical parameters of the new 'stuff'. In the electronics lab, oscilloscopes, voltmeters, spectrum analyzers, light analyzers are all used to measure electrical parameters. In the chemist' lab, gas chromatographs, mass spectrometers, and other instruments are used.

Perhaps you've seen some of the CSI shows on TV. The crime scene investigator uses instrumentation to find out what materials are made of, DNA sequences of body fluids, and other analyses.
