确定了目标重量值，则马上可得到限位值：下限限位值TU1为464g。但考虑产品包装的平均重量值为472g，少部分产品包装欠重只要不*过规定的量值仍然是允许的。包装袋标签净重值为454g，查规定300g-500g的产品可允许短缺量为3%，即11.62g，可将下限限位值设定为462g，此时剔除率为0.62%。上限限位值TO1可按下限限位值与目标重量值的对称关系定为482g，也可根据剔除数量的百分比要求设定，当*重产品无须剔除时，也可不设定上限限位值。例2：某产品目标重量值为1203g，限位值设定为：TU1为1191g，TU2为1173g，TO1为1215g，TO2为1233g。查表11-1可知允许短缺量是产品净重的1.5%，这大致是1200×0.15=18g，现在目标重量值与TU1相差12g，远小于允许短缺量；目标重量值与TU2相差30g，差值不是TU1差值两倍的关系；该检重秤的标准偏差值σ为4.452g，3σ约为13.4g，也大于12g。限位值是按现场运行情况设定的。从图中数据可见，剔除的产品数13占该批产品总数212的6%，偏大了一点，而产品重量的平均值为1204.16g，则较为理想。用作重量检验的检重秤在投运前要对设定值进行设定，这关系到检重秤的正常运行，也关系到减少溢装量、提高企业的经济效益，应该受到检重秤运行维护人员的重视。本文探讨的几种检重秤限位值和设定值设定方法可供大家参考西门子模块代理商|潮州PLC模块代理商

加料装置加料454g的变化值为13g，产品包装的重量数据接近理想的正态分布，其平均重量值为477g，标准偏差为4g。由于平均重量值远*过包装袋的“标签重量”(毛重)值，*装量偏大，故按“标签重量”(毛重)值加2倍标准偏差8g来确定目标重量值，即为464+8=472g，包装产品重量等于大于464g比例为97.73%，即2σ范围内的概率95.45%再加上余下比例的一半(*重、欠重各占一半)的2.28%，此时欠重部分为2.27%。西门子模块代理商|潮州PLC模块代理商
