Document Type and Number:
WIPO Patent Application WO/2019/013089
Kind Code:
A1
Abstract:
[Problem] To provide a pressure detection device capable of limiting erroneous detection of the pressure of a medium inside a tube. [Solution] A pressure detection device 30 can be installed on a tube 11 transporting a medium BL and detects the pressure of the medium BL inside the tube 11. Said device is provided with: a body 31 that can be fitted on the tube 11; an image acquisition unit 32 that is provided on the body 31 and acquires image information of a pressure-bearing part that deforms when subjected to the pressure of the medium BL inside the tube 11; and a controller 100 that converts the image information acquired by the image acquisition unit into pressure information relating to the pressure.
