【摘要】 国家强震动台网使用的力平衡加速度传感器属于强检仪器范围,依据该台网运行与维护规程须每年校准一次。但是近年来我国中强等级的地震频发,由于台网没有备机替换,故无法将服役的传感器分批分期送到计量部门检测,急需一种检测传感器性能现场检定的解决方案。本文针对上述要求,选择北京、河北地区正在服役的传感器进行实验,通过现场与实验室对仪器灵敏度的检测结果进行分析和对比,得出了一种适用于服役传感器现场检测的方法。更多还原

【Abstract】 Sensors used in the Force-Balance Accelerometer belong to the scope of mandatory inspection of the instruments,which shall be calibrated once a year according to the specification. But strong earthquakes occur frequently in our country in recent years,therefore,the Force-Balance Accelerometer cannot be sent to metrological service to be tested in batches. In order to detect the performance of these instruments,on-site test methods are badly-needed. Based on the above requirements,the Force-Balance Accelerometers which are serving in Beijing and Hebei province are chosen,and the sensitivity of these instruments is detected. Thus,an online testing technology is acquired through analysis and comparison of on-site and laboratory test results of these instruments.更多还原
