Abstract
In an electronic balance for application in potentially explosive areas, the weighing system, the electronic evaluation unit and the digital display unit have an intrinsically safe design with regard to the possibility of explosions. All lead connections are supplied with low voltages and the power unit when present is located outside the electronic balance and connected to the electronic balance via an explosion-safe lead and plug connections with an intrinsically safe design with regard to an explosion. In an alternative the power unit can be encapsulated in a pressure-proof manner, powder-filled, force-ventilated or located outside the potentially combustible gaseous explosive area. It is also contemplated that a battery which is intrinsically safe with regard to explosions can also be used in the housing of the electronic balance instead of a separate power unit.
