Systems, methods, and apparatus for connection fault self-monitoring with DC bias current

摘要

Certain embodiments of the invention may include systems, methods, and apparatus for providing connection fault self-monitoring with dc bias current. According to an example embodiment of the invention, a method is provided for obtaining measurements and detecting connectivity faults associated with a voltage mode sensor. The method can include coupling a DC bias current (322) into a circuit (240). The circuit includes a voltage mode sensor (202), and the voltage mode sensor (202) can output a time varying signal (323). The method can also include setting a nominal level of the DC bias current (322), monitoring a voltage (324) associated with the DC bias current (322), and determining circuit connectivity status based at least in part on monitoring the voltage (324).
