The history of instrumentation can be divide into several phases.
===Pre-industrial===
Elements of industrial instrumentation have long histories. Scales for comparing weights and simple pointers to indicate position are ancient technologies. Some of the earliest measurements were of time. One of the oldest [[water clock]]s was found in the tomb of the [[ancient Egypt]]ian pharaoh [[Amenhotep I]], buried around 1500 BCE.<ref>{{cite web | title = Early Clocks | url = https://www.nist.gov/pml/general/time/early.cfm | accessdate = 1 March 2012}}</ref> Improvements were incorporated in the clocks. By 270 BCE they had the rudiments of an automatic control system device.<ref>{{cite web | title = Building automation history page | url = http://www.building-automation-consultants.com/building-automation-history.html
In 1663 [[Christopher Wren]] presented the Royal Society with a design for a "weather clock". A drawing shows meteorological sensors moving pens over paper driven by clockwork. Such devices did not become standard in meteorology for two centuries.<ref>
