PLUG-AND-PLAY SENSOR PERIPHERAL COMPONENT FOR PROCESS INSTRUMENTATION

摘要

A plug-and-play sensor peripheral component includes an electrically conductive physical connector; an electrical connector; a transformer; and an RF communication and data storage circuit. The electrical connector is electrically connected to the physical connector by a first conductive path. The transformer is electrically connected to the RF communication and data storage circuit. The transformer and the RF communication and data storage circuit are electrically isolated from the physical connector and the electrical connector. Electrically connecting the physical connector to the electrical connector by other than the first conductive path inductively couples the RF communication and data storage circuit to the first conductive path.
