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 parallel construction, particularly for a top-loading balance with elecmagnetic force compensation, has two essentially identical, preferably trapezoidal, movable guides in parallel horizontal planes. The guides are mounted permanently at one end and connected together by a movable rigid connecting element at the other end. The two guides are displaced relative to one another in their planes at right angles to their axis of rotation.

摘要： An electric inclination meter is built into a high-resolution electric balance with a measured value receiver, a microprocessor for digital signal processing and with a digital display. This inclination meter compensates the inclination-dependent errors of the balance. The inclination meter can have a movable suspended mass or it can have a container which is partially filled with liquid, thus forming a gas bubble. The positional deviation of the movable elements can be picked up optically or inductively.

摘要： In a spring body which is manufactured from a cubical piece, intended for a balance with an upper scale, divided into an upper and a lower guide bar by a horizontal opening extending all the way through it so that the spring body also forms the parallel guide for the balance scale, and which has wire strain gauges at thin spots in the areas of at least one guide bar the width of the spring body is divided at least in the area of the guide bars into two partial areas by a vertical opening which extends all the way through it and does not contact the edge. The vertical opening can have various shapes. The wide spring body has the advantages of in sensitivity to errors caused by off center loading and allowing the scale to be connected to the parallel-guided part of the spring body at two or three points, which reduces the stability requirements of the scale. The strain gauge are advantageously distributed so that one half of them is on each of the two areas of spring body. The strain gauges can be applied in various configurations.

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.

An accessory circuit is provided for modifying at least the last digit appearing on the display device in response to an arrest criterion or a condition of the balance, such as an open measuring chamber or position of a draft shield. The criterion can be developed from comparing successive measured values.
