Process control is an engineering discipline that deals with architectures, mechanisms and algorithms for maintaining the output of a specific process within a desired range.

For instance, the temperature of a chemical reactor may be controlled to maintain a consistent product output.

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.

The scope and application of a measurement is dependent on the context and discipline.

In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures.

However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales.

Precision is a description of random errors, a measure of statistical variability.

Accuracy has two definitions:

A machine is a tool containing one or more parts that uses energy to perform an intended action.

Machines are usually powered by chemical, thermal, or electrical means, and are often motorized.

Historically, a power tool also required moving parts to classify as a machine.

However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

A gauge or gage, in science and engineering, is a device used to make measurements or in order to display certain information, like time.

A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery.

Depending on usage, a gauge can be described as "a device for measuring a physical quantity", for example "to determine thickness, gap in space, diameter of materials, or pressure of flow", or "a device that displays the measurement of a monitored system by the use of a needle are pointer that moves along a calibrated scale".
