液态铅铋合金(LBE)中溶解氧浓度的精确测量是实现LBE中氧浓度控制的前提。本文用一自主研制的Bi/Bi_2O_3型氧传感器来测量LBE氧浓度,在静态氧饱和的LBE中分别进行了准确性及稳定性测试。准确性测试结果表明,在340~480℃范围内氧传感器电动势实验曲线随温度的变化与理论曲线一致,电动势绝对误差最大为-2.6 mV;稳定性测试结果表明,在450℃、50 h内电动势绝对误差为 -1.4 mV,波动为4 mV。 |

Accurate measurement of the concentration of dissolved oxygen in liquid leadbismuth eutectic(LBE)is the premise to achieve oxygen control.A self-developed Bi/ Bi_2O_3 oxygen sensor was used to measure oxygen concentration in LBE.The accuracy and stability tests were carried out in stagnant liquid LBE in the condition of oxygen saturation. The accuracy test results show that the change of experimental electromotive force with temperature is consistent with the theoretical curve in the temperature ranging from 340℃ to 480℃.The maximum absolute error of electromotive force is -2.6 mV.The stability test results show that the absolute error of electromotive force is -1.4 mV within 50 hours at the temperature of 450℃ and the fluctuation in this test is 4 mV. |
