    摘要: A force measuring device, such as a weighing device, having device for automatically compensating for temperature-induced zero and span deviations. The device includes force and temperature sensors for producing force and temperature indicative signals, respectively. Device for processing processes these force and temperature signals at various temperatures in no-load and reference-load conditions by regressive analysis in order to obtain and store in memory equations representing the zero and span deviations with temperature. During use of the force measuring device for measurement, the device uses the stored equations to calculate the zero and span deviations from the current temperature to correct the force indicative signal.

    摘要: A force measuring device mainly used as a weighing device, comprising first and second horizontal cantilever members disposed parallel with each other in a common vertical plane, a weighing cradle attached to the free end of the first member, and a metal string stretched between the free ends of both members. The string is placed between a pair of magnetic poles so that it vibrates at its inherent frequency functionally relating to its tension and, therefore, a load applied to the weighing cradle. The frequency of the string is measured and the value of the applied load is calculated therefrom by an electronic calculating circuit. In order to overcome a problem of frequency deviation caused by variation in the spring constants of both cantilever members due to variation in the surrounding temperature, the inventive device includes a temperature sensor and arithmetic circuitry for applying compensation for the error due to the temperature change to the calculation of the applied force.
