Abstract
Description
또, 종래에는 본 출원인 및 발명자에 의해 개발 된 것으로 '자장 거리측정용 휴대용 자장 탐지기'(대한민국 공개특허공보 공개번호 특2002-0072829)가 알려져 있다.
여기서는 피 물체가 자석인지 아닌지를 시청각으로 학인 할 수 있고 자장 거리도 측정할 수 있도록 한 형태이며, 여기서는 마그네트스위치가 하나뿐에 설치하지 않아 하나 뿐인 마그네트스위치가 외부 충격이나 휴대중 또는 측정 중 손에서 지면으로 떨어지면 접점이 떨어지는 현상이 발생될 수 있어 좀더 신뢰성 있는 자장 탐지기를 제공하는데 문제가 있다.
Claims (1)
- 표시램프(14), 부저(16), 밧데리(18)가 내설된 본체(12)를 포함하는 마그네트탐지기에 있어서,상기 본체(12)의 전방에는 하나의 마그네트스위치가 전기적으로 손상되면 다른 하나가 스위치 작동되는 마그네트스위치(20)(21)를 이중으로 설치한 것을 특징으로 한 교습용 마그네트 탐지기.
