Abstract
According to the present disclosure, at least two fluid inlet/outlet pipes, each of which is provided with a filter, are installed outside a structure to be bent and an end of each of the fluid inlet/outlet pipes is connected to a pressure sensor provided on the structure. Thus, since a fluid in the state in which low-frequency and high-frequency components of the disturbances generated outside the structure are removed therefrom acts on the pressure sensor, the underwater pressure sensing apparatus is capable of measuring fluid pressure in a stable state.
Claims10
An underwater pressure measurement apparatus for measuring pressure under water, the apparatus comprising:
- a structure having a configuration in which an interior and an exterior are separated from each other such that inflow of a fluid is blocked;
- a pressure sensor configured to measure pressure of the fluid and installed inside the structure;
- and
- two or more fluid inlet/outlet pipes, each formed in a hollow shape such that the fluid flows into or flows out of the two or more fluid inlet/outlet pipes, each of which is connected, at one end thereof, to the pressure sensor and is provided, at a remaining end, with a filter configured to block inflow of foreign matter and to remove a high-frequency component of a disturbance, the two or more fluid inlet/outlet pipes being made of a bendable material and being disposed outside the structure, wherein when the fluid flowing into the fluid inlet/outlet pipes through the filter acts on the pressure sensor, a high-frequency component and a low-frequency component of the disturbance generated in water are removed while passing through the filter and the fluid inlet/outlet pipes.
