Abstract
A wireless process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of the industrial process. Measurement circuitry connected to the process variable sensor provides an output related to the sensed process variable. Wireless communication circuitry connected to the measurement circuitry wirelessly transmits information related to the sensed process variable to a remote location. A removable industrial power module is configured to hold a replaceable battery and provide power to the process variable sensor, the measurement circuitry and the wireless communication circuitry. Battery test circuitry in the removable industrial power module connects to the replaceable battery and provides a visual output related to a condition of the replaceable battery.
