Abstract
In an electromechanical weigher to be used in areas subject to explosion hazards, the electronic indicator ledge and the weigher apparatus or weighing system is constructed explosion proof in an intrinsically safe manner, and the power supply in the case is on all sides partitioned by means of bulkheads, and the free space enveloping these constituents is filled with an explosion-impeding granulate e.g. of quartz. For the use as dosing weigher for prescription weighings in such areas subject to explosion hazards, the indicator ledge is constructed by means of a hollow support engaging the case above the weigher dish and above a tare vessel of the usual height to be put on the weigher dish, as horizontal indicator constituent running approximately parallel to the weigher back, and the indicator constituent is tiltable at the support about a horizontal shaft in which structure the electric supply lines are passed from the indicator edge through the hollow support, into the inside of the case. The indicator constituent is furthermore provided with switches and operating keys which together with the indicator ledge ae explosion proofed in an intrinsically safe manner. For school and demonstration purposs, the indicator constituent is provided with two synchronically connected electronic indicator ledges, one pointing to the frontside and one to the backside of the weigher, which indicator ledges are arranged in a mutually parallel position inside the indicator constituent.
