钇稳定二氧化锆火焰传感器的静态响应特性

以钇稳定二氧化锆（YSZ）火焰传感器为研究对象，利用马弗炉，在873~1 523 K的温度范围内，测量了YSZ火焰传感器对温度的静态响应，获得并分析了传感器的静态校准曲线与静态响应特性。结果表明，YSZ火焰传感器的线性度为12.88%，24 V激励电压下的平均灵敏度为10.02 mV/K，迟滞与重复性指标分别为2.13%和2.22%，传感器间的互换度为1.22%。采用Boltzmann函数能够较为准确地拟合YSZ火焰传感器的静态校准曲线，误差小于±3.5%。YSZ火焰传感器的非线性特征明显，精密度与互换性良好，灵敏度较高，总体性能良好。相较于火焰检测中常用的热电偶和离子火焰传感器，YSZ火焰传感器对火焰温度的响应信号更为稳健，能够有效提高火焰检测的准确度与可靠性。 

Static response performance of yttria-stabilized zirconia based flame sensor

By the use of a muffle, the static response of the yttria-stabilized zirconia (YSZ) flame sensor to temperature was measured in the range of 873-1 523 K, and the static calibration curve and response characteristics of the sensor were obtained and analyzed. The results show that the linearity of the YSZ flame sensor is 12.88%; with 24 V excitation voltage, the average sensitivity is 10.02 mV/K; the indexes of hysteresis and repeatability are 2.13% and 2.22%, respectively; the interchangeability between different YSZ flame sensors is 1.22%; the static calibration curve of the sensor can be accurately fitted by the Boltzmann function with an error of less than±3.5%. The YSZ flame sensor has significant nonlinearity, high sensitivity, good precision and interchangeability, and the overall performance is good. Compared with thermocouples and ion-based flame sensors commonly used for flame detection, the output signal of the YSZ flame sensor in response to the flame temperature is steady and robust, which can effectively improve the accuracy and reliability of flame detection.
