选择扭矩传感器时的主要考虑因素是选择合适的量程:如果选择的量程过小,容易出现过载,造成传感器感应体塑形变形;如果选择量程过大,则容易出现测量精度不足或是分辨率不足。

在确定系统的最大平均扭矩后,需按如下方式设定安全系数。旋转扭矩测量中,不同应用场景对扭矩传感器的冲击程度各异。选择系统最大峰值扭矩时,必须综合考虑"驱动"与"负载"系数。负载工况系数(LSF)定义了不同负载类型:
LSF 1
平稳运行设备(恒定转速)→ 风机、液泵
LSF 2
非恒定负载→ 起重机、输送机、挤出机、混合机
LSF 3
轻度反向负载→ 破碎机、单体泵、车辆传动系统、锤磨机
LSF 4
剧烈扭矩交变负载→ 往复式压缩机
同时需考虑驱动工况系数(DSF)对预期最大峰值扭矩的影响:
DSF 0
平稳运行的直流或三相交流电机
DSF 0.5
8缸汽油或10缸柴油发动机、单相交流电机
DSF 1
6缸汽油或8缸柴油发动机、三相交流电机
DSF 1.5
4缸汽油或6缸柴油发动机、单相变频控制交流电机
DSF 3
小于4缸汽油或6缸柴油发动机
预期峰值扭矩 = 平均运行扭矩 × ( LSF + DSF )
举个例子:
平均运行扭矩:200 Nm
负载: LSF 3 (汽车传动轴)
驱动: DSF 1.5 (6缸柴油发动机)
预期峰值扭矩 = 200 Nm × ( 3 + 1.5 ) = 900 Nm。
所以为了保护传感器,应该考虑1 KNm的量程扭矩传感器。但是这时如果实际测试扭矩较小,会造成测量精度不足问题。对此,奇石乐的4503B(轴式)和455x(法兰式)系列产品可以切换为1:10的第二段量程解决方案。


100 Nm的4503B扭矩最大误差通常为满量程的0.05%,即0.05 Nm。但是在0-10 Nm范围内,最大误差不超过10 Nm的0.1%,即0.01 Nm。直接把传感器测量误差减小为1/5。

由于此特质,
客户可在精确量程内进行测量以获得更佳精度,获得更精确的测量结果
测量较小试样时可节省传感器更换时间
节省额外联轴器和工装
最终为客户提供更灵活和更经济的测量解决方案。
