| Abstract: | In the high radioactive environment, pneumatic components have the advantages of explosion-proof and high reliability, but the compressibility of the gas leads to the delay of the gas pressure signal transmission, resulting in the decrease of the sensitivity of the gas pressure sensor. Through theoretical analysis and experimental verification on the relationship between the pipeline and pressure response of the air pressure sensor, this paper analyzes the causes of signal lag of air pressure sensor, the gas transfer behavior of long tube is analyzed, and according to the experimental results, the gas transfer model is optimized, finally gives the improvement scheme of air pressure sensor sensitivity. |
