摘要
叙述了无触点磁敏电位器的内部结构及其工作原理。无触点磁敏电位器是心电图机磁敏传感式位置反馈记录器的核心部件之一,对心电描记的正常工作起着重要作用。如果磁敏电位器出现问题,将会导致心电图机出现描笔单偏等故障。在分析了其常见故障的基础上,阐述了静态和动态两种检测方法,最后提出了检修和保养方面的参考建议。
The inner structure and operating principle of non-contact magneto potentiometer are described. The noncontact magneto potentiometer is one of the main parts of the electrocardiographic magnetic sensing position feedback recorder, which is important for the electrocardiograph to operate normally. If magneto potentiometer has any problem, it will result in some faults. Based on the analysis about the common faults, static method and dynamic method are provided. At last, some suggestions and reference are presented for detection and maintenance.
