固体电解质SO_2（SO_3）传感器测定烟道气中的SO_2

本文论述了利用北京科技大学研制的固体电解质ＳＯ２（ＳＯ３）传感器对测定烟道气中的ＳＯ２进行的研究。利用该传感器测定烟道气中的ＳＯ２，其测量范围为：５０—１７０００ｍｇ／ｍ３，相对标准偏差小于４．０％。因而具有测量范围宽，精确度高以及稳定性好的特点。设计的试验样机的总体噪声和漂移小于１．０ｍｇ／ｍ３，同时具有体积小．重量轻和操作简单的特点。

Determination of SO_2(SO_3) in stack gas with solid-state electrolyte SO_2 sensor

This paper describes the determination of SO2(SO3)in stack gas with solid-state electrolyte SO2 sensors which were developed by University of Science and Technology.Results show that with this kind of sensor, concentrations ranging from 5.0 to 17000 mg/m3 of SO2(SO3)in slack gas can be detected with good stability and high precision(the relative standerd deviation is less than 4.0% at the whole experimental range).The designed experimental device based on this method has the features of simplicity,low weight and small volume with low noise and drift(both of them are below 1.0mg/m3).
