Abstract
It's difficult to detect the weak signal of electrostatic sensor which is used to measure the parameters of dilute gas-solid two phase flow. To solve this problem, based on the analysis of basic principle and signal characteristic of electrostatic sensor, a weak signal detection circuit with high-resolution was developed. The result indicates that the circuit has a very high resolution, extremely low temperature drift and strong anti-jamming ability towards stray capacity and external electric field. The given circuit can satisfy the requirements for parameter measurement of gas-solid two phase flow.
