摘要
主流电阻式加热器件产品,在加工过程中受各种因素影响,使其常温阻值不均,控温精度差,成品率低,装配的烟具需二次单个调试等,对加热器件性能评价几无报刊。以市售主流加热器件为研究对象,参照电阻温度传感器参数测定及阶跃响应法,采用A类不确定度数据处理及评价方法。建立加热器件性能评价参数体系及加热器件一致性评价方法。3.4 V的阶跃电压条件下,测试多片加热器件中点位置特性参数。C1、C2稳态温度差51℃,一致性差;其余加热器件基础参数标准偏差σn<0.1,稳态温度残差≤4℃,A类测量不确定度un<3,一致性好。表明了建立的加热器件性能评价参数体系及一致性评价方法实用性和有效性。
Popular resistance heating element products are affected by various factors during the processing process,making their normal temperature resistance uneven,poor temperature control accuracy,low yield rate,assembled smoking sets need to be individually debugged twice.There are few newspapers and periodicals evaluating the heating element performance.Taking the popular heating elements in the market as the research object,referring to the resistance temperature sensor parameter measurement and step response method,A-type uncertainty data processing and evaluation methods are used.Establish heating element performance evaluation parameter system and heating element consistency evaluation method.Under the condition of 3.4 V step voltage,test the characteristic parameters of the midpoint position of multiple heating elements.C1,C2 steady-state temperature difference 51℃,poor consistency,standard deviation of basic parameters of other heating elements isσ_n<0.1,steady-state temperature residual error is≤4℃,class A measurement uncertainty is u_n<3,good consistency.It shows the practicability and effectiveness of the established heating element performance evaluation parameter system and consistency evaluation method.
