【Abstract】 Based on the concept of point charge, the experimenta l device of electrostatic induction was designed. The effects of dimensions of the ring probes on the characteristics of the gas-solid two phase flow sensors wer e studied. The experimental results showed that the shorter is the length of the ring probe, the wider is the frequency band of the sensor , but the smaller is the energy transfer ratio. So, the influences of frequency bandwidth and energy transfer ratio on the measurement result should be considered in sensor designs.更多还原
