Abstract

A field device (100) is disclosed that includes a pair of electrodes (138,140) coupled to a process fluid (128) and a diagnostic circuit (156) coupled to the pair of electrodes (138,140) to monitor a common mode signal. The diagnostic circuit (156) is adapted to detect a poor ground connection associated with at least one electrode of the pair of electrodes (138,140) based on line noise associated with the common mode signal.
