Description

유도성 근접 센서
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명 센서의 기본적인 다이어그램, 제2도는 제1도의 다이어그램에 관계하는 전압 전류의 시간 그래프, 제3도는 제1도 코일의 단자에서 유도된 전압에 속하는 제2도의 상세한 확대도.

Claims (6)

  1. 코일에 전달하기 위한 코일 수단과, 검출될 물체 부재에 응답하여 발생이 가능한 신호를 측정하고 처리하기 위한 수단을 구비하는 유도성 근접 센서에 있어서, 상기 전달 수단은 주기 T의 주기 전류를 갖고 코일에 공급하기 위해 배열되며, 코일에 대해 전달 수단에 의해 유도된 전류는 T보다 적은 존속시간 T1에 대해 후자에 따르며 상기 주기의 나머지(T-T1)에 대해 거의 제로의 값을 가지며, 상기 신호를 측정하고 처리하기 위한 수단은 주기의 전술된 나머지 시간(T-T1)에 대해 검출된 물체의 존재에 응답을 발생하도록 배열되는 것을 특징으로 하는 유도성 근접 센서.
  2. 제1항에 있어서, 상기 신호를 측정하고 처리하기 위한 수단은(T-T1)보다 작거나 같은 시간 주기 T2동안에 코일의 단자에 고유전압을 측정하기 위해 배열된 것을 특징으로 하는 유도성 근접센서.
  3. 제1항에 있어서, 상기 전달 수단은 주기의 나머지 시간(T-T1)에 대해 거의 제로값을 갖기 위해 코일의 전류를 강제시키는 스위치를 구비하는 것을 특징으로 하는 유도성 근접센서.
  4. 제1항 또는 제2항에 있어서, 상기 코일은 저항(4)과 병렬로 접속되며, 상기 저항의 값은 대략 큰 것을 특징으로 하는 유도성 근접센서.
  5. 선행항중 어떤 한 항에 있어서, 상기 센서의 코일은 2개의 부분으로 부분되는 중간 출력을 가지며, 상기 권선 방향은 반대 위상으로 유도된 2개 부분의 전압 합과 동일한 결과의 유도 전압을 발생하도록 배열된 것을 특징으로 하는 유도성 근접센서.
  6. 제1항 내지 제5항에 있어서, 주기 T의 주기적 전류의 제어신호 SI1은 주기 T4의 주기 신호의 T의 주기 신호의 멀티플리 케이션에 의해 얻어지며, 증폭후 센서의 응답 신호는 제거될 증폭기(5)에 의해 도입된 DC성분을 허용하는 필터 수단(6)에 접속된 것을 특징으로 하는 유도성 근접 센서.
