Modern measuring devices and systems are able to process measurement results using mathematical methods and transmit them over long distances. Various signals (electrical, magnetic, acoustic, light, etc.) are used in measuring systems. Today, new durable measuring devices and systems have been created in almost all areas based on microelectronic elements. Also, pulsed and digital measuring devices are widely used in a wide range of industries, production and services. This science is a science that studies and develops methods and means of recording quantities that represent production processes, properties and states of objects under investigation, and covers issues of solving problems arising in measuring methods and instruments in order to improve the quality and competitiveness of product production and service provision.
