操作:
該發(fā)現(xiàn)光學探測器有一個白色模壓聚碳酸酯外殼,帶有防風的煙霧入口。這兩個指示燈是紅色警報。箱內(nèi)有一個印刷電路板,它的一邊是防光室,周圍是光學測量系統(tǒng),另一邊是信號處理和通信電子。其準直器內(nèi)的紅外線發(fā)光二極管設(shè)置在光極管的鈍角處。這種光極管有一個整體的阻止日光的濾波器。
The IR LED emits a burst of collimated light every second. In b air the photo-diode receives no light directly from the IR LED, because of the angular arrangement and the chamber baffles. When smoke enters the chamber it scatters light from the emitter IR LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed to provide an analogue value for transmission when the detector is interrogated.
