Title:
UNDERWATER PRESSURE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/151338
Kind Code:
A1
Abstract:
An underwater pressure measurement device is disclosed. The underwater pressure measurement device, according to the present invention, relates to measuring pressure underwater and comprises: a structure element having a structure, in which the inside and the outside are separated such that the introduction of fluid is blocked; a pressure sensor formed to measure the pressure of the fluid and installed inside the structure element; and two or more fluid inlet and outlet tubes formed in a hollow shape so as to allow the fluid to flow in and out, each of which one end is connected to the pressure sensor and the other end is provided with a filter for blocking the introduction of foreign matters and removing the high frequency components of disturbance, and made of a freely bending material so as to be arranged outside the structure element, wherein when the fluid introduced into the fluid inlet and outlet tubes through the filter acts on the pressure sensor, the low frequency components and the high frequency components of disturbance generated underwater are removed while passing through the filters and the fluid inlet and outlet tubes. According to the present invention, the two or more fluid inlet and outlet tubes having the filters are mounted to be bent outside the structure element, and the one end portion of each of the fluid inlet and outlet tubes is connected to the pressure sensor provided in the structure element, such that the fluid in a state, in which the high frequency components and the low frequency components of disturbance generated outside the structure element are removed therefrom, acts on the pressure sensor, thereby providing the effect of measuring, by the pressure sensor, the pressure of the fluid in a stabilized state.
