This document provides an overview of measurement and instrumentation concepts for a mechanical engineering course. It defines key terms like variable, parameter, measurement system, and experimental test plan. It describes the four main elements of a measurement system: the sensing element, signal conditioning element, signal processing element, and data presentation element. Specifically, it gives examples of common sensors, transducers, and ways of presenting measurement data. The overall purpose is to introduce students to the fundamental principles and components involved in taking mechanical measurements.
