Instruments & Control

Instruments are the variety of measuring instruments to monitor and control a process. It is the art and science of measurement and control of process variables within a production, laboratory, or manufacturing area. It is the development or use of measuring instruments for observation, monitoring or control. An instrument is a device that measures a physical quantity, such as flow, temperature, level, distance, angle, or pressure. Instruments may be as simple as direct reading hand-held thermometers or as complex as multi-variable process analyzers. Although instrumentation is often used to measure and control process variables within a laboratory or manufacturing area, it can be found in the household as well. A smoke detector is one example of a common instrument found in many western homes.
