    Abstract

    AbstractSensitive magnetic field sensor based on compensated double pick up coil has been developed. In order to confirm sensitifity of modified design, experiment carried out in two steps. Firstly, sensitify of conventional design is clarified. Here pick up coil as an active sensor and solenoid as an exitation coil is separately made. Secondly, modified sensor of integrated configuration is developed. Here for both active flux gate sensor and the exitation coil is made in same one core magnetic. Ferrite and standar foil soft magnetic is utilized in this experiment. In attention, frequency of 50 Hz i s used for the whole experimens. A result showed that sensitvity of the integrated configuration sensor is much larger than conventional one. Then, power consume of the integrated flux gate sensor is much lower than conventional. Finally, a range measurement of the integrated configuration sensor can be realized less than 20 T which potential may perhaps sense a change of natural local magnetic field. Keywordsdouble pick up coil, hysteresis curve, magnetic field AbstrakSensor medan magnet sensitif berbasis double pick up coil terkompensasi telah dikembangkan. Untuk konfirmasi sensitifitas desain modifikasi sensor yang akan dibuat, ekperimen dilakukan dengan dua tahap. Pertama, sensitifitas desain konvensional diklarifikasi. Pada konfigurasi ini, pick up coil sebagai bahan aktif sensor dan kumparan sebagai koil eksitasi dibuat masing-masing terpisah satu dengan lainnya. Kedua, modifikasi sensor dalam bentuk konfigurasi terintegrasi dikembangkan. Pada desain ini, baik sensor aktif flux gate dan koil eksitasi dibuat pada satu inti magnetik. Ferrite dan inti besi lunak standar digunakan pada eksperimen ini. Untuk perhatian bahwa frekuensi 50 Hz digunakan pada keseluruhan rangkaian eksperimen. Hasil menunjukkan bahwa sensitifitas dari sensor konfigurasi terintegrasi jauh lebih besar daripada konfigurasi konvensional. Kemudian, konsumsi daya dari flux gate sensor terintegrasi juga lebih rendah daripada sensor konfigurasi konvensional. Akhirnya, jangkauan pengukuran dari sensor konfigurasi terintegrasi dapat direalisasikan lebih kecil daripada 20 T yang berpotensi bisa mengindera suatu perubahan medan manget lokal alami. Kata Kuncidouble pick up coil, kurva histeresis, medan magnet
