【摘要】 本文从传感器检定时如何保证准确地测量其输出信号的角度出发,分析了过去几年我国检定MAREX浮标传感器工作中在测量方面存在的问题,介绍了为解决这些问题而研制的“HJF1-1型浮标传感器检定用测量装置”的工作原理、基本组成和设计思想,并列举了两个实例比较不同测量、计算方法对检定结果的影响,从而提出了在海洋环境自动监测系统的传感器检定工作中一个值得注意的普遍性问题。更多还原

【Abstract】 Problems of measurement occurred in calibrating the sensors on MAREX data buoy during the past few years in China are analysed from the point of view how to accurately measure the output signals when the sensors are being calibrated. The principle of operation, basic components and design considerations of theHJF 1-1 calibration device for sensors on data buoy developed for solving the above mentioned problems are outlined herein.Two examples are given for comparing the effects on the result of calibration using different methods of measurement and calibration.A common point which should be paid attention to in sensor cali- bration for automatic marine environmental monitoring systems is stressed at the end of the paper.更多还原
