INDUSTRIAL PROCESS FIELD DEVICE WITH IMPROVED BATTERY ASSEMBLY

摘要

An industrial process field device (200) is provided. The device (200) in cludes wireless process field device electronics (412; 512; 612; 712; 812) d isposed within the industrial process field device (200) and at least one ba ttery cell (326; 442; 552; 652; 742; 842) disposed within the industrial pro cess field device (200) and operably coupled to the wireless process field d evice electronics (412; 512; 612; 712; 812). A circuit (400; 500; 600; 700; 800; 900) is provided that senses an electrical characteristic related to th e at least one cell (326; 442; 552; 652; 742; 842) and provides an output to a switch (418; 518; 610; 718; 818) to decouple the at least one cell (326; 442; 552; 652; 742; 842) from the industrial process field device electronic s (412; 512; 612; 712; 812) in response to certain conditions. Such conditio ns include too much current flowing from the at least one cell (326; 442; 55 2; 652; 742; 842); the voltage of the at least one cell (326; 442; 552; 652; 742; 842) being too low; or a short circuit being generated or otherwise ob served.
