Abstract:
1. An energy supply unit for a measuring device for determining and/or monitoring a physical or chemical, process variable of a medium, comprising: at least one energy source provided in the energy supply unit; at least one capsule unit provided in the energy supply unit; at least one voltage limiting unit; and/or at least one current limiting unit, wherein: said at least one energy source and said at least one voltage limiting unit and/or said at least one current limiting unit being located in said at least one capsule unit said at least one voltage limiting unit is embodied in such a manner that arising voltages remain below a value that leads to an explosion in an explosion-endangered area, and/or said at least one current limiting unit is embodied in such a manner that arising currents and/or heatings associated therewith remain below a value that leads to an explosion in an explosion-endangered area.
