摘　　要：在发动机、实验装置、仪器仪表等设备中,厚膜铂电阻用来测量与监控温度变化,若元件阻值输出异常,会使测温精度下降或无法反馈信号,甚至造成更大的经济损失。本文通过对厚膜铂电阻在装配时出现电阻值输出异常故障进行分析、观察,定位故障原因,制定防护优化措施,并进行试验验证措施有效,顺利解决了输出异常故障。In engines,experimental devices,instruments and other equipment,thick-film platinum resistors are used to measure and monitor temperature changes.If the output of component resistance is abnormal,the temperature measurement accuracy will decrease or the signal cannot be fed back,and even greater economic losses will be caused.In this paper,through the analysis and observation of the abnormal output fault of thick-film platinum resistor during assembly,the cause of the fault is located,the protection optimization measures are formulated,and the tests are carried out to verify that the measures are effective and the abnormal output fault is successfully solved.
