Zusammenfassung:	A wireless field device for use in controlling or monitoring an industrial process, includes a process interface configured to couple to a process fluid. Field device circuitry is coupled to the process interface and configured to measure or control a process variable. Wireless communication circuitry is configured to provide wireless communication. At least one electrical access terminal is configured to provide an electrical connection to circuitry of the field device. A power supply is configured to power the wireless field device. The power supply includes a removable primary power source to provide power to the field device for extended periods of time. A secondary power source is configured to provide power to the field device when the primary power source is removed.
