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 .
Military instruments as a class draw on most of the categories of instrument described throughout this article, such as navigation, astronomy, optics, and imaging, and the kinetics of moving objects. Common abstract themes that unite military instruments are seeing into the distance, seeing in the dark, knowing an object's geographic location ...
Instrumentation and control engineering is a vital field of study offered at many universities worldwide at both the graduate and postgraduate levels. This discipline integrates principles from various branches of engineering, providing a comprehensive understanding of the design, analysis, and management of automated systems.
Digital instrument meter with digital display. Only numbers are shown at a digital display. Analogue instrument meter with digital display. Only numbers are displayed, but through a mechanical or electro-mechanical display (today very rare but has existed for clocks, certain Doppler meters and informational screens at many stations and airports)
Instrument mechanics in engineering are tradesmen who specialize in installing, troubleshooting, and repairing instrumentation, automation and control systems.The term "Instrument Mechanic" came about because it was a combination of light mechanical and specialised instrumentation skills.
Instruments used to measure and display pressure mechanically are called pressure gauges, vacuum gauges or compound gauges (vacuum & pressure). The widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge.
The precise way in which they are constructed varies, with the main types of mechanical planimeter being polar, linear, and Prytz or "hatchet" planimeters. The Swiss mathematician Jakob Amsler-Laffon built the first modern planimeter in 1854, the concept having been pioneered by Johann Martin Hermann in 1818. [ 1 ]
A micrometer, sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw widely used for accurate measurement of components [1] in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
