Measurement and control basics pdf
Instrumentation and control engineering - WikipediaThis is the first of a series of technical articles about instrumentation and control. In this series, we will discuss the basic concepts and principles that govern the operation of industrial plants. Concepts associated with measurements of flow, level, temperature and pressure, electronics and pneumatics instrumentation, control loops, PID control, and others will be addressed. Someone once asked a colleague what his occupation was. He replied without hesitation, "I am an instrumentation and control engineer. I'm in trouble," thought the engineer.

Measurement and Control Basics, 4th Edition
Instrumentation is defined as the art and science of measurement and control of the process variables within a production or manufacturing area. Control engineering or control systems engineering is the engineering discipline that applies control theory to design systems with desired behaviors. The practice uses sensors to measure the output performance of the device being controlled and those measurements can be used to give feedback to the input actuators that can make corrections toward desired performance. When a device is designed to perform without the need of human inputs for correction it is called automatic control such as cruise control for regulating a car's speed. Multi-disciplinary in nature, control systems engineering activities focus on implementation of control systems mainly derived by mathematical modeling of systems of a diverse range. This term refers to the graduate discipline many universities provide at graduate and postgraduate level. Instrumentation and Control 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 Basics: Measurement Terminology. Instrumentation is the science of automated measurement and control. Applications of this science abound in modern research, industry, and everyday living. From automobile engine control systems to home thermostats to aircraft autopilots to the manufacture of pharmaceutical drugs, automation is everywhere around us. This piece will focus on the fundamental principle of measurement terminology. The objective of any measurement endeavour is to be able to measure a given process variable in order to possibly control it. Hence what you cannot measure, you cannot control.
