自动气象站SL3-1型雨量传感器特殊故障修复处理

摘要

The maximum allowable error of rainfall sensors for automatic weather stations is 10 ±0.4 mm and the common error is the over-tolerance rainfall records,namely the abnormal rainfall records from rainfall collectors or generated by computers.Through the years use and maintenance practice,some experiences are accumulated; for example,by adjusting the base,namely changing sensor measurement tipping bucket deflection angle,the error usually can be controlled within the allowable range.Two cases of the SL3-1 rainfall sensor faults are described,in which regular/irregular multi-count over-tolerance records are processed properly.%自动气象站雨量传感器的最大允许误差为每10 mm降雨误差±0.4 mm,运行中常见故障为雨量记录超误差,即采集器记录或计算机生成的雨量比实际值偏多或偏少.通过近几年的使用维护,积累了一些经验.例如,在确定是传感器原因时通过调整基点,即改变传感器计量翻斗的偏转角度,通常情况下可将误差控制在允许范围内.介绍的SL3-1型雨量传感器两例特殊故障的处理,是指在调整计量翻斗误差调整螺钉无效果的情况下,对传感器有规则多计数和无规则多计数超误差故障的修复处理.
