Abstract
The invention relates to an electronic balance for use in an explosive environment. The invention calls for an intrinsically safe cable (1) which contains data lines in addition to the voltage supply lines. The data is serially transferred on the data lines. A first conversion unit is housed in the housing of a power pack which conversion unit receives the data arriving serially via the cable (1), converts it into parallel data and stores it so that it can be passed on in a parallel and asynchronous manner in the non-explosive area, that a second conversion unit is housed in the housing of the power pack which second conversion unit stores the data arriving in parallel manner from the non-explosive area, converts it into serial data and sends it serially via the cable (1) into the explosive area, and that the control unit (3) also contains at least a first conversion unit which receives the data arriving serially via the cable (1), converts it into parallel data, stores it and passes it on in parallel manner to the evaluation unit. The control unit contains at least one second conversion unit which stores the data arriving in parallel manner from the evaluation unit, converts it into serial data and sends it serially via the cable (1).
