Physical Instrument

A device that measures a physical phenomenon or parameter. At a minimum, it possesses a detector which produces a signal from which the desired quantity is calculated or inferred. The detector signal possesses the information needed to either obtain the value of the phenomenon (e.g, temperature: a voltage is converted into a temperature unit) or infer its value using further processing and computation (magnetic fields: detector intensities at a different wavelengths and polarization states are processed to infer a magnetic field strength). An instrument does not necessarily require a way to store its measured quantity (e.g, a hard disk).
