Title:
CASING AND CAP ASSEMBLY FOR MARINE HOSE FLUID LEAK DETECTOR AND MARINE HOSE FLUID LEAK DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/024124
Kind Code:
A1
Abstract:
Provided are: a casing and cap assembly that makes it possible to improve the durability of a detector, reduces the risk of damage to both the detector and an object as a result of contact therebetween, and makes it possible to maintain a suitable wireless communication state with the detector; and a marine hose fluid leak detection system comprising the assembly. In a casing 18 in which a pressure sensor 15 and an IC tag 12 are accommodated in a pressure-holding chamber 18c formed by a substrate 18a and a radio wave-transmitting section 18b, three or more metal protruding sections 19 with spaces therebetween in a circumferential direction at outer circumference-side positions of the radio wave-transmitting section 18b in a planar view are made to protrude from the substrate 18a above the radio wave-transmitting section 18b, the top end sections of the protruding sections 19 are spaced apart from each other, and while in a state in which an annular cap 20 made from a resin or rubber covers the upper ends of each of the protruding sections 18 so as to be continuous in the circumferential direction and is fixed to the casing 18, an inner circumference-side area and an outer circumference-side area with respect to each of the protruding sections 19 communicate via a gap between the lower end sections of the protruding sections 19 adjacent in the circumferential direction.
