  • Patent number: 4457386
    Abstract: A weighing system of the electromagnetic load compensation type is disclosed including a counter for counting the weight-responsive pulses which are produced during the periods that the compensating current is supplied to the movable coil to return the movable scale member toward its initial no-load position, characterized by the provision of a temperature-responsive device for supplying to the counter a train of temperature-correction pulses that are used to modify the count of the weight-responsive pulses, whereby a more accurate indication of the applied load is obtained. Thus, an analog signal from the temperature sensor is compared with a sawtooth signal to produce a digitalized temperature-responsive signal which modifies the digital weight signal supplied to the microprocessor circuit.
