摘　　要：选用了3SF定电位电解型传感器作为二氧化硫连续在线监测探头.通过对该传感器各项特性指标的研究表明:该传感器在0～2 500 mg/m3测量范围内,输出信号线性相关系数为0.998 9,零点漂移为0.64%F.S.,相对准确度最大偏差为28 mg/m3,响应时间为30s,以上特性符合国家HJ/T 76-2001标准中对二氧化硫传感器的各项指标要求,试验研究表明该传感器可用于二氧化硫连续在线监测.The 3SF fixed electric potential electroanalysis sensor was chosen as the online continuous detector of boiler sulfur dioxide emission. The investigation indicated that: at the scale of 0~ 2 500 mg/m 3, the relatively coefficient of output signal is 0.9989; the zero shift is 0.64% of full scale; the maximum relatively error is 28 mg/m 3; response time is 30 s. These characters conformed to the requests of sulfur dioxide sensor in the HJ/T 76-2001 Criterion. The investigation demonstrated that this sensor can be used as the online continuous detector of sulfur dioxide emission.
