The gas limiting alarm miner's lamp circuit is composed of the detection amplifier circuit, and the circuit is shown as the chart. RP uses synthetic carbon potentiometer. C1 ~ C4 select aluminium electrolytic capacitor with the withstang voltage being more than 6.3V. VD1 and VD2 use 1N4007 or 2CP22 silicon rectifier diodes. VS selects 2CW11 silicon regulator diode. V1 ~ V5 and V7 select 59013 or 3DK4 silicon NPN transistors; V6 uses 59012 or 3CG21 silicon PNP transistor; V8 and V9 select 58050 silicon NPN transistors. K uses 4099 or JRC-5M DC relay. The sensor uses carrier catalytic gas sensor. Power switch S, miner's lamp EL, battery CB are the accessories of the original miner's lamp.
