Instrumentation is a collective term for measuring instruments used for indicating, measuring, and recording physical quantities.
Field of science and technology, a branch of mechanical engineering engaged in the development and production of measuring instruments, processing, and presentation of information, automatic and automated control systems.
The main direction of the development of instrumentation is measuring technique, which consists of methods and devices for measuring mechanical, electrical, magnetic, thermal, optical, and other physical quantities. Measuring instruments together with automatic control and actuating devices form the technical basis of automated process control systems.
