This note describes a digital circuit for the measurement of combustion intermittency in fire gases. The measurement has been achieved by analyzing the positive ion current drawn by an electrostatic probe immersed in the flow. The circuits used are modular in design so that signals from different types of sensor may be presented for intermittency analysis. Some results obtained in an unbounded diffusion flame are reported.
