Set of one or more measuring instruments and often other devices, including any reagent and supply, assembled and adapted to give information used to generate measured quantity values within specified intervals for quantities of specified kinds.
Three main components compose a measuring systems:
– sensor. It transforms the changes of measured variable into variations of an electrical one;
– system of control. It is expected to perform the following functions:
* acquisition of the signals coming from the sensor at preset intervals;
* any local storage of data;
* data transmission.
– supply system.
