    摘要: An adapter (300) for coupling to a process control transmitter of the type used to monitor a process variable in an industrial process is provided. The adapter includes I/O circuitry (342) configured to couple to a two wire process control loop (302) and to the process control transmitter and communicate on the process control loop (302). Wireless communication circuitry (344) couples to the two wire process control loop (302) and is configured to transmit an RF signal. Power supply circuitry (350) provides power to the wireless communication circuitry.
