ABSTRACT
In measurement and monitoring, there always has been a need to employ devices with the classical requirements, such as the communication capabilities, data processing, fault analysis, conŸguration guidance, performance tracking and enhancement, calibrations, dri£ monitoring, convenient access to devices, network management, and security. Most modern intelligent sensors and instruments address these requirements as will be explained in this chapter. Emphasis will be given tointelligent sensors since they represent the state of art of this technology.
