The Smart Wireless THUM™ Adapter acts as an extension of the HART function of the primary mA output
on your Micro Motion transmitter. It broadcasts HART data from the transmitter to the Wireless HART

™

primary mA output. The Smart Wireless THUM Adapter is shipped integrally mounted to the Micro Motion
transmitter.
