石英谐振式称重传感器的可靠性增长模型

Reliability Increment Model of Quartz Resonator Loda Cell

石英谐振式称重传感器是一种新型的数字式传感器。文中通过对该传感器研制和生产中的可靠性增长试验，找到了传感器的系统缺陷，并通过修正传感器的结构来消除这种传感器的系统缺陷，使之可靠性水平（ＭＴＢＦ） 达到使用的要求。通过建立传感器老炼过程的可靠性增长模型，为生产过程的筛选次数提供依据。

This paper describes reliability of a novel type of sensor.In order to find system fault of this sensor,reliability increment tests were done and reliability increment modal-AMSAA BISE was set up based on these tests.System fault was fixed by modifying structure of sensor and life of this sensor (MTBF)reaches 10 5 times after screening.
