Abstract

Disclosed is a field device adapter for wireless data transfer, comprising: an adapter housing having a first and a second end, the first end such that the field device adapter can be mechanically connected to a field device and the second end such that a two-wire cable can be connected to the field device adapter. The adapter housing also having an adapter chamber; a supply electronics unit arranged in the adapter chamber and designed to provide a supply voltage via a voltage tap; an adapter electronics unit; and an adapter connection cable at the first end for connecting the adapter electronics to a field device electronics. The adapter electronics are designed to communicate the two-conductor signals between the field device electronics and the two-conducting-wire cable and also to convert the two-conductor signals into radio signals or vice versa.
