Instrumentation refers to the tools and devices used to measure, control, and analyze physical quantities in various fields such as engineering, science, and medicine. These instruments can include sensors, gauges, and meters that help gather data about temperature, pressure, flow, and other parameters. In the context of medical instrumentation, devices like ultrasound machines and MRI scanners are used to diagnose and monitor health conditions. In industrial settings, instrumentation is crucial for ensuring processes run efficiently and safely, often involving automated systems that enhance productivity and accuracy.
