摘要： A wind guard for a balance is suggested which consists of at least two cylindrically curved wall elements, in which each wall element is connected to a corresponding segment of the circular covering surface. In this manner, the balance scale is readily accessible both from the side and also from above when the wind guard is open.

摘要： In an analytical balance with scale on top with a scale carrier which is directly operatively connected to the measured value receiver, with a balance scale disk (6) which rests in a removable manner on the scale carrier, with a weighing chamber which surrounds the balance scale disk (6), the scale carrier and the measured value receiver, with a weighing chamber lock which constitutes the communication between the weighing chamber and the environment and which consists of two sets of closing doors or elements located in a vertically displaced manner in the form of a lock and with a transport device which can move the balance scale between a weighing position on the scale carrier and a loading position outside of the weighing position on the scale carrier and a loading position outside of the weighing chamber, the two closing elements of the weighing chamber lock are located above one another. The lower closing element consists of at least one level, horizontal plate which can be shifted in the plate plane. The upper closing element consists of at least one level plate or of a cylindrically bent plate which can be shifted in the plate plane or in the cylinder surface. The transport device for the balance scale disk moves the latter essentially vertically.

摘要： It is necessary, when high requirements are demanded from balances, that the effect of different disturbance variables such as, e.g., temperature and/or moisture on the measuring system be corrected. To this end, temperature and moisture sensors are used from whose output signal correction values are calculated. The invention suggests that a storage area be provided into which the instantaneous measured results of these sensors are stored in succession, where they remain stored for a set time. This data stemming from different times, evaluated with set weighting factors, could then be used to calculate the corrections. This makes it possible to obtain a good correction of changing disturbances even with a different behavior in time of sensors and measuring system.

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： The invention indicates a balance with counting scale in which the resolution of the balance with counting scale can be increased in the determination of the reference weight of light pieces without an additional switching key operated from the outside. To this end, a comparator (14) is present in the built-in electronic circuitry which is actuated when the transfer key (8) is pressed and which frees the transfer of the weight into the memory (16) and the determination of the average individual weight when a set threshold is exceeded, while, when this threshold is dropped below, it does not free the transfer of the weight into the memory and increases the resolution of the balance by a given factor.
