拉力机质量好坏的判断标准
拉力机拉伸试验是研究材料力学强度最广泛使用的方法之一，需要使用恒速运动的。按载荷测定方式的不同，早期大体可以分为摆锤式拉力试验机和电子拉力试验机两类，目前摆锤式拉力试验机市场上现在很少有人使用,主要是精确度满足不了现在的标准要求,购买拉力机是为了通过qs认证达到国家标准,是为了检测自己的产品，提高产品的质量，开拓市场。选购时如何判断标准拉力机质量的好坏,主要可以参考以下资料:
一、传感器：因为传感器的好坏决定了试验机的精度和测力稳定性，传感器的也有大小的区分，市场上的拉力机用传感器小力值一般用S型传感器，大力值一般用轮輻式传感器，传感器内部一般为电阻应变片式，如果应变片精度不高或固定应变片用的胶抗老化能力不好在或者传感器的材料不好都将影响传感器的精度和使用寿命。
