Research and Verification of the Foam Thickness Measurement Method Based on the Microwave Transmission Method
摘要
Abstract
In order to realize the automatic measurement of foam thickness in foam drainage gas extraction process,a foam thickness measurement method based on microwave transmission method is proposed.The structure of foam thickness measurement based on microwave transmission method is designed,which includes the transmitting end and receiving end.The transmission characteristics of microwave in foam are analyzed,and the theoretical model of foam thickness measurement is formed;An axial in-mode ceramic helical antenna is designed by using the electromagnetic simulation software of CST.The physical model of foam thickness measurement based on microwave transmission method is simulated in CST,and the relationship between the thickness of foam and the return loss of the antenna is obtained.The feasibility of the foam thickness measurement method based on the microwave transmission method is verified by experiments.The test results show that the designed spiral antenna operates at a frequency of 1.35 GHz with a gain of 8.31 dB,and the resolution of foam thickness measurement is 2 mm.关键词
