Field Instruments

Welcome to the frontlines of Industry 4.0. Field instruments combine sensors, actuators, intelligent signal processing, and robust communications while often operating in the harshest of environments. They are required to capture and interpret data that is communicated to the cloud at the enterprise level. It is there that algorithms and analytics turn this data into insights and actions. But the understanding realized in the cloud is only as good as the data captured at the node, so quality matters. Today’s legacy 4-20ma field Instruments have inherent power constraints that can limit the ability to meet Industry 4.0 demands for increasing edge intelligence, safety, and security. ADI is bringing innovative power solutions, advanced sensing capability, precision measurement, safety through diagnostics, and more intelligence to front-line sensing and control within automation.
