This makes it possible to obtain a high output signal from the wire strain gauge in the case of a corner load without the stability of the parallel guide being adversely affected.

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： The invention suggests an intermittent mode of operation to reduce the stray power in the coil in a balance based on the principle of the electromagnetic compensation of force. To this end, switching means (21) are provided which can interrupt the current flow through the coil (11) so that when the current flow is interrupted, the movable parts (2-9) of the balance move against one of the stops (24) or (25). These switching means (21) are controlled by the digital signal processing unit (18). In addition storage means (20) are provided within the framework of the digital signal processing unit which store the last-determined weight value for the duration of the interruption of the current flow through the coil.
