Abstract

An adapter (300) for coupling to a process control transmitter (308) of the type used to monitor a process variable in an industrial process includes a first connection configured to couple to a first side of a two wire process control loop (302), a second connection configured to couple to a second side of the two wire process control loop (302) and in series with a first connection to a process control transmitter (308), and a third connection configured to couple to a second connection of the process control transmitter (308). Wireless communication circuitry is coupled to at least the third connection and is configured to provide wireless communication for the process control transmitter (308). Intrinsic safety circuitry (460) coupled to at least one of the first, second and third connections is configured to limit transfer of electrical energy to a value which is less than an intrinsic safety value.
