[0022]实施例1：

[0023]一种应变式传感器与信号处理装置的匹配方法，包括应变式传感器、弹性体和信号处理装置，应变式传感器包括应变片或者电磁式传感器，弹性体是作为直接传递力的装置；在生产阶段，将应变式传感器与弹性体组合为力传感器，对力传感器进行测试、标定并导出弹性系数值；在装配阶段，将力传感器与信号处理装置进行随机组装，然后将力传感器的弹性系数值传输至与其匹配的信号处理装置；采用本实施例的方法，在生产阶段不需要将力传感器与信号处理装置一一匹配，则力传感器与信号处理装置可以分开生产，分类管理，以利于提高质量，而且信号处理装置可以使用统一工艺生产，无需匹配对应的力传感器标定校准，能够降低生产过程的复杂性，从而提高生产效率；在装配阶段，力传感器与信号处理装置可以随机组装，无需匹配，安装结束后将弹性系数值传输至信号处理装置即可，不仅能够提高装配效率，而且能够降低使用过程中的不匹配风险。

[0024]具体地，将应变式传感器与弹性体组合为力传感器，给定不同压力值，使用工具测试不同压力下传感器的输出信号，即进行标定校准，然后使用软件计算出应变式传感器与弹性体匹配的弹性系数值；本实施例中在生产阶段对力传感器进行统一的测试和标定，然后导出弹性系数值，直接形成标准的生产工序，无需信号处理装置的介入，操作方便，能够提高生产效率。

[0025]具体地，在生产阶段，将弹性系数值生成为图形编码；在装配阶段，采用扫描装置对图形编码进行扫描，然后将得到的弹性系数值传输至信号处理装置；优选地，在生产阶段，将弹性系数值生成为图形编码，然后将图形编码标记至弹性体上；本实施例中将弹性系数值生成为图形编码，然后标记在弹性体上，不需要额外的存储介质，保存方便且不会丢失，在装配时，操作方便，有利于提高装配效率；优选地，图形编码采用激光直接标记在弹性体表面，实现永久标记，便于维修；当然，在其他可选的实施例中，也可以将图形编码打印成标签，然后将标签粘接在弹性体上，或者将图形编码标记至力传感器的合格证或者说明书上，在此不作限制。

[0026]优选地，图形编码包括二维码，信号处理装置包括无线传输模块，扫描装置与信号处理装置之间采用无线传输；具体地，扫描装置可以采用手机或者其他移动扫描终端，无线传输模块优选地蓝牙模块；例如，一般手机内都会带有蓝牙模块，这样便于与信号处理装置进行无线连接，然后用手机扫描弹性体上的二维...

[0027]实施例2：

[0028]一种力传感器，其包括应变式传感器和弹性体，弹性体上设置有图形编码，图形编码承载有力传感器的弹性系数值，优选地，图形编码为二维码；图形编码采用激光标记在弹性体表面，或者弹性体上粘贴有标签，标签上印刷有图形编码；本实施例中的力传感器应用实施例1中的匹配方法，使得力传感器可以作为一个独立的产品进行生产和销售，不需要与信号处理装置进行捆绑，而信号处理装置可以自产或者采购，能够提高生产效率，而且可以对力传感器或者信号处理装置单独进行更换或者维修，能够降低成本。
