A dosing device with a balance, which includes a weighing chamber (); a processor (); a climate module (), which is disposed in the weighing chamber (); a data transmission path, over which data is exchanged between the climate module () and the processor (); and a mixing formulation display (). Also disclosed are a climate module configured to electrically couple to a dosing device in a detachable manner, wherein the climate module () forms a self-contained modular unit and includes various sensors () and a path over which data is transmitted to a processor external to the climate module, and a method for mixing a formulation, using a dosing device, wherein ambient conditions are detected during dosage of the substances to be combined, and the mixing ratio is adjusted in accordance with the detected ambient conditions.

Dosing device with integrated balance and climate module

An electronic scale () with a display unit (), at least one control button (), a digital signal processing unit () and a digital interface () to a higher-level electronic data processing (EDP) system (). The digital signal processing unit () has an activatable switch or program part for locking the scale. This switch or part releases the display of the weighing result only for as long as the higher-level EDP system () communicates with the scale () and locks the display at other times. The activation of the switch or part for the locking process is stored in a power-failure-proof memory ().

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).
