摘要：本文針對(duì)衡器在各個(gè)行業(yè)使用的共同特征，設(shè)計(jì)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(yīng)變計(jì)，直接采用電阻應(yīng)變儀做為終端讀數(shù)器。討論了衡器尺寸的設(shè)計(jì)方法，并制造了一個(gè)樣機(jī)對(duì)標(biāo)準(zhǔn)砝碼進(jìn)行了實(shí)際測(cè)試。模型實(shí)際測(cè)試結(jié)果顯示該裝置具有較高的測(cè)量精確度，并且該裝置的設(shè)計(jì)方法可以推廣到大量程的衡器設(shè)計(jì)中。

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
