Claims (3)
- 화염이 발하는 가시광을 검지하는 반도체 수광소자와, 케이블을 통해 상기 반도체 수광소자에 그 구동전압을 공급하는 동시에 상기 케이블을 통해 상기 반도체 수광소자에 의한 화염검지신호를 검출하여 화염의 유무를 판정하는 검출장치 본체를 구비하고,상기 반도체 수광소자와 상기 케이블 사이에 역접속 방지용 다이오드를 직렬로 끼워 삽입하는 동시에, 상기 검출장치 본체에 상기 화염의 유무를 판정하는 제1의 임계값에 더하여, 상기 반도체 수광소자의 역접속 및 단락을 각각 판정하는 제2 및 제3의 임계값을 설정하는 화염 검출부를 구비한 것을 특징으로 하는 화염검출장치.
- 제 1항에 있어서,상기 반도체 수광소자는, 포토다이오드와 상기 포토다이오드의 출력을 증폭하는 증폭기를 구비한 것을 특징으로 하는 화염검출장치.
- 제 1항에 있어서,상기 검출장치 본체는, 서로 직렬접속되어 구동전원에 접속된 제1 및 제2의 저항기를 구비하고, 상기 제1 또는 제2의 저항기의 양단 사이에 상기 케이블을 통해 상기 반도체 수광소자를 병렬접속한 것으로서,상기 제1 및 제2의 저항기에 의해 전원전압을 저항분할하여 상기 반도체 수광소자의 구동전압을 생성하는 동시에, 상기 제1의 저항기와 상기 제2의 저항기의 접속점에 생기는 전압을 판정하여 화염의 유무를 판정하는 것을 특징으로 하는 화염검출장치.
