SL2-1型雨量传感器测量误差调整方法探讨

SL2—1型雨量传感器是—种在借鉴国外先进技术的基础上研发出的一种新型单翻斗雨量传感器，它以结构布局合理、科学，测量准确度高而倍受广大用户的推崇。我国气象装备部门研发的单雨量自动观测站，有相当一部分采用该雨量传感器作为测量降雨量的基本传感器。为保证全国范围内所有雨量自动观测站所观测到的雨量准确、可靠，以及其观测数据具有可比性，定期开展雨量传感器的检定与维护，将雨量观测值的误差控制在允许范围内，是气象计量保障中的一项非常重要的工作。本文从单翻斗雨量传感器的结构原理入手，重点介绍传感器的超差调整方法和日常维护，作为实际观测和检定时为参考。

Measuring Error Adjusting and Routing Maintenance on Model SL2-1 Rainfall Sensor

Model SL2-1 rainfall sensor is a new-type single tipping-bucket rainfall sensor which is developed basing on the advanced experience of foreign countries for reference. It is held in esteem because its designing is reasonable, scientific and high accuracy. At single rainfall observation station which is developed by China meteorological department, it is widely used as a rainfall sensor. In order to ensure the accuracy, reliability and the comparable of the observate data, verify an maintain the rainfall sensor in a certain period and control the error in an allowed area, are the important work in the measurement an maintenance. In this article, according to the constructive principle, error adjusting method and routing maintenance will be introduced in details, as a reference in testing and observation of the rainfall sensor.
