摘要： In a drying balance with scale on top and with a radiation source for heating and drying material to be weighed located on the balance scale, the radiation source (11) is permanently located behind the balance scale (5) and a bent cover (7) which functions as a radiation deflector is movably located over the balance scale (5). This makes the construction lower and a moving of the radiation source (11) with its electric connections is avoided when the balance scale (5) is loaded. Moreover, differently constructed inner surfaces (7') of the cover (17) permit the drying balance to easily adapt to different radiation sources (11) and to different drying tasks.

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： An electromagnetic, compensating force-measuring or weighing device having at least one working coil movable in an air gap of a magnet system. At least two members for temperature compensation are positioned at different, spaced apart points. The compensating effect of these members on the active part of the system jointly produce a temperature compensating value which is optionally approximately equal to the exact value of the actual temperature curve. The members may be in the form of a plurality of minute particles of nonretentive material having a high negative coefficient of saturation magnetization distributed in the active part. The members may be formed of the afore-mentioned material and be positioned on the active part or be PTC or NTC resistors so positioned.

摘要： A drying balance with a radiation source (11) for heating and drying a substance distributed on a balance scale (5), with a temperature sensor (8) for monitoring and controlling the output of the radiation source (11) and with electronic evaluating circuitry (33) for evaluating the measured values of the balance and for controlling the drying balance that a temperature gauging disk (14) with another temperature sensor built in be used in order to determine in a temperature gauging cycle the deviation of the output signal of the temperature sensor (8) from the output signal of the other temperature sensor built into the temperature gauging disk (14) and to calculate a correction factor from them and to store this correction factor. Then, the output signal of the temperature sensor (8) is multiplied by this correction factor during dryings in order to obtain the true temperature of the substance. Different coefficients of absorption of different substances can be mimiced by surfaces on the temperature gauging disk which exhibit different sizes and a high absorption capacity or a low absorption capacity.
