More Information
Summary:A wireless field device assembly comprises a process sensor, a housing, a power module, and a processor. The process sensor is configured to monitor a process variable and produce a sensor signal. The housing encloses an interior space of the wireless field device. The power module comprises an energy storage device and a connection to a local power source, and is configured to be housed in the wireless field device. The processor is located within the interior space, and is powered by the power module. The processor produces a fault signal value used to differentiate between energy storage device faults, local power source faults, and no-fault states.
