摘要： Apparatus for measuring weight and force has a load reception part arranged for deflection on a fixed part of a weighing and force-measuring system and includes a compensation coil arrangement situated in a constant magnetic field. At least one position sensor ascertains load-dependent deflections of the load reception part from a predetermined position and feeds a sensor signal to an electric regulator circuit. The regulator circuit regulates the current through the compensation coil arrangement so that the load reception part is returned to its predetermined position. The regulator circuit includes means which impart, alternately, positive and negative values, determined by the loading, to the current flowing through the compensation coil arrangement.

摘要： Electronic weigher apparatus is disclosed which utilizes a plate situated below the weighing scale and above a load receiver which is part of an electronic weight measuring system. The plate is shaped in such a way that thermal air currents generated by the electronic apparatus are carried through a low air resistance path from the interior to the exterior of the weigher casing while a high resistance airflow path prevents air currents from being carried upward from the electronic apparatus to the weighing scale. A collar encircling the scale prevents external air currents from disturbing it during the loading operation.

摘要： 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.
