    Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities.It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory.

  3. Instrumentation in petrochemical industries - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_in...

    Some instrumentation is self actuating. For example, pressure regulators maintain a constant pre-set pressure, and rupture discs and pressure safety valves open at pre-set pressures. [3] Instrumentation includes facilities for operating personnel to intervene in the plant either locally or from a control room.

    The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

  7. Embedded instrumentation - Wikipedia

    en.wikipedia.org/wiki/Embedded_Instrumentation

    In the electronics industry, embedded instrumentation refers to the integration of test and measurement instrumentation into semiconductor chips (or integrated circuit devices). Embedded instrumentation differs from embedded system , which are electronic systems or subsystems that usually comprise the control portion of a larger electronic system.

  8. Biofeedback - Wikipedia

    en.wikipedia.org/wiki/Biofeedback

    The definition reads: Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance. Precise instruments measure physiological activity such as brainwaves, heart function, breathing, muscle activity, and skin temperature.
