Collecting and sending information about a measured variables
Examples includr pressure sensors (such as bellows,daiphragms,manometers,anf bourdon tubes), temlerature sensors(such as, thermometers, thermal bulbs,thermocouples,thermiistors, and resistance themperature dectectors, level sensors(such as orifice plate and venturi tubes when used eith a differential pressure sensors,and royameters.)
Displaying and/or recording information about a measured variable.
Instruments that display information include thermostats,speedometers
