Abstract:
An industrial process field device is provided. The device includes wireless process field device electronics disposed within the industrial process field device and at least one battery cell disposed within the industrial process field device and operably coupled to the wireless process field device electronics. A circuit is provided that senses an electrical characteristic related to the at least one cell and provides an output to a switch to decouple the at least one cell from the industrial process field device electronics in response to certain conditions. Such conditions include too much current flowing from the at least one cell; the voltage of the at least one cell being too low; or a short circuit being generated or otherwise observed.
