[0017] See figure 1 with 2 , The present invention relates to an online nanofiber film thickness measurement device, which is provided with a pneumatic pump 1, an air filter 2 (thread specification: G1 / 4), a fixed-value pressure reducing valve 3 (AR2000), and a throttle valve 4 ( LSA8 regulating valve, diameter: 8mm), HVFF8 pneumatic switch valve 5, cylinder 6, pressure sensor 7 (measuring range: 0-2.5KPa), data acquisition and processing system 8, working platform 10, lifting rod 11, screw rod 12, Polished rod 13, supporting net 14, sealing ring 15. The gas output by the pneumatic pump 1 passes through the air filter 2, the fixed-value pressure reducing valve 3, the throttle valve 4, and the pneumatic switch valve 5 in order to obtain the predetermined pressure gas, and then flows into the cylinder 6, and the lower threaded hole of the cylinder 6 is connected Pressure sensor 7. The pressure sensor 7 is connected to the data acquisition and processing system 8. The air cylind...
