本文阐述了仪表可靠性的定义、与MTTF(失效前平均时间)和失效率等其他耐久性指标之间的关系。讨论了现代仪表的可靠性要求。对可维修仪表与不可维修仪表的可靠性作了定量分析。论及了改善仪表可靠性和有效性的各种措施。其中,对冗余和维修两种措施作了详尽的讨论,并以模拟量仪表领域中冗余措施的特殊形式作为例证。最后,讨论了预防性维修和正确维修及其效果。
This article describes the definition of instrument reliability and its relationship to other durability measures such as MTTF (Mean Time Before Failure) and Failure Rate. Discuss the reliability requirements of modern instruments. Quantitative analysis of the reliability of repairable instruments and non-repairable instruments. Discussed various measures to improve the reliability and effectiveness of instruments. Among them, the two measures of redundancy and maintenance were discussed in detail, and the special form of redundancy measures in the field of analog meters as an example. Finally, preventive maintenance and proper repairs and their effects are discussed.
