摘要：本文針對衡器在各個行業使用的共同特征，設計了適用于小量程的懸臂梁式稱重裝置，在懸臂梁上粘貼電阻應變計，直接采用電阻應變儀做為終端讀數器。討論了衡器尺寸的設計方法，并制造了一個樣機對標準砝碼進行了實際測試。模型實際測試結果顯示該裝置具有較高的測量精確度，并且該裝置的設計方法可以推廣到大量程的衡器設計中。
關鍵詞：電阻應變計；衡器；懸臂梁

Abstract: This paper designed a narrow-range cantilever steelyard in view of the common ground on the instrument applications in variety regions, which the resistance strain gauge installation used as reading monitor，as the resistance strain gauges were glued on the cantilevers. The design method
of the instrument was discussed in this paper, and the machine was manufactured to have a test with the standard weights. The result of model testing showed that the weighing apparatus could be enough precise to measure weight and this design method could be applied to produce great-range steelyard.
Key words: Resistance strain gages; Weighing apparatus; Cantilever beam
