Abstract
PURPOSE:To prevent the lower limit of sodium ionization detection from deteriorating at ageing time by superimposing a fluctuation signal of a sodium ionization detector (SID) and a reference wave of high frequency not superimposed with the frequency band of the SID signal and calculating the mean frequency of the signals. CONSTITUTION:The signal from a sodium ionization detector (SID) is superimposed with a sine wave (reference wave) of relatively high frequency from a sine wave generator 9 to thus obtain a DC output corresponding to the mean frequency by a mean frequency arithmetic circuit 10. The circuit 10 consists of a reactive value arithmetic circuits 80, 81, a differentiator 11 and a divider 12. Thus, it is obtained a sodium ionization detector which has no variation and solid difference due to ageing and installing positions at the lower limit of detecting by the SID and high response.
