Instrumentation is the branch of engineering that deals with measurement and control.According to ISA, the official definition of Instrumentation - is a collection of Instruments and their application for the purpose of Observation, Measurement and Control. Reference: ISA std. S 51.1 (Instrument Society of America)

An instrument is a device that measures or manipulates variables such as flow, temperature, level, or pressure. Instruments include many varied contrivances which can be as simple as valves and transmitters, and as complex as analyzers. Instruments often comprise control systems of varied processes. The control of processes is one of the main branches of applied instrumentation.

Control instrumentation includes devices such as solenoids, valves, circuit breakers, and relays. These devices are able to change a field parameter, and provide remote or automated control capabilities.

Instrumentation plays a significant role in both gathering information from the field and changing the field parameters, and as such are a key part of control loops.

Instrumentation can be used to measure certain field parameters (physical values):

These measured values include:

  • pressure, either differential or static
  • flow
  • temperature - Temperature measurement
  • level - Level Measurement
  • density
  • viscosity
  • radiation
  • frequency
  • current
  • voltage
  • inductance
  • capacitance
  • resistivity
  • chemical composition
  • Nuclear composition (Mass spectroscopy)
  • chemical properties
  • various physical properties
