The cited article says the term has its origins in the art and science of scientific instrument-making, and that instrumentation can refer to devices as simple as direct-reading thermometers or as complex as multi-sensor components of industrial control systems. Instruments recorded in the atlas as measurement or metrology instruments are grouped under this concept.
