<p>希望大家通过本文的介绍,可以对拉力传感器原理等方面的内容有一定的认识与了解,下面就跟随深圳市力准传感技术有限公司的专家一同来看一下相关的内容简?p style="text-indent:2em;">拉力传感器基于这样一个原理:弹性体(弹性元件,敏感梁)在外力作用下产生弹性变形,使粘贴在他表面的电阻应变片(转换元件)也随同产生变形,电阻应变片变形后,它的阻值将发生变化(增大或减小),再经相应的测量电路把这一电阻变化转换为电信号(电压或电流),从而完成了将外力变换为电信号的过程?/p><p style="text-indent:2em;">  考虑到使用地点的策略加速度和空气浮力对转换的影响,拉力传感器的性能指标主要包括有线性误差、滞后误差、重复性误差、蠕变、零点温度特性和灵敏度温度特性等?/p><p style="text-indent:2em;">  拉力传感器的优点是精度高,测量范围广,寿命长,结构简单,频响特性好,能在恶劣条件下工作,易于实现小型化、整体化和品种多样化等。它的缺点是对于大应变有较大的非线性、输出信号较弱传感器,拉力传感器原理但可采取一定的补偿措施。因此它广泛应用于自动测试和控制技术中?/p><p style="text-indent:2em;"> <span

3.考虑当有设备最大出力时(伺服电机,气缸等出力等有过冲?,需要考虑过冲力对传感器的的影响,因此在选择时传感器的量程要大于过冲力的2倍以?/p><p style="text-indent:2em;">  B、传感器的精度拉?<b>测力传感?/b>的选型</p><p style="text-indent:2em;">  1 传感器的精度要根据测量系统对测力传感器的要求来选取</p><p
