3軸磁界測定器による船内磁界の測定

抄録

The authors have been studying about an immovable type magnetic course indicator with an electrical deviation corrector. In process of this study, characteristics of the magnetic sensors and the values of ship's magnetic field became neccesary to be precisely measured. We designed a magnetic sensor of flux-gate type and a set with three axes about (fore and aft, port and starboard, top and bottom), then examined about its characteristics. While, ship's magnetic fields are meaured on UMITAKA-MARU and HAKUSAN-MARU at sea. This paper describes ability test for magnetic sensor that make use of three dimensional magnetic field detectors and measured results on ship's magnetic field using the new instrument.
