Title:
構造体における負荷を測定するシステム、測定ユニット及び測定センサ
Document Type and Number:
Japanese Patent JP4156833
Kind Code:
B2
Abstract:
The invention relates to a system for measuring loading, stresses and/or material fatigue in a structure. The invention also relates to a measuring sensor unit (50) and a measuring sensor (302) suitable for use in connection with said method. The invention is applicable especially to the measurement of stresses and loading on a ship hull. One inventive idea is that the measuring sensor unit (50) of the measuring system comprises means (310) for processing a signal from the sensor so as to allow complete mathematical measuring results to be transmitted (316, 21) from the measuring sensor unit to the central processing unit. Another inventive idea is to form a measuring sensor from the sensor assembly and the strain gauge so that deformations are transmitted to the strain gauge attached to an elastic area of the sensor assembly. By means of the invention, the measuring units can be calibrated apart from the structure material and additional measuring units can be provided in the system whenever necessary.
