Kayan aikin aunawa na nesa na methane na Laser JJB30

1, Bayani
Kayan aikin auna nesa na methane na laser ya ƙunshi ƙananan tsarin guda biyu: tsarin watsawa da karɓar laser da tsarin sarrafa sigina. Tsarin watsawa da karɓar laser ya ƙunshi hasken laser guda biyu. Ɗaya shine laser infrared don gano iskar gas, ɗayan kuma shine laser ja/kore da ake gani wanda ake amfani da shi don nuna alkibla da nisan aunawa. Lokacin da mai amfani ya danna maɓallin "MEASURE", laser infrared mara ganuwa da laser mai nuna ja/kore mai kama da alkalami mai nuna alama suna fara aiki akai-akai. Laser infrared da ƙarshen watsawa ke fitarwa yana sha ta iskar methane lokacin da yake wucewa ta cikin iskar gwaji, ɗayan kuma na hasken yana nuna komawa zuwa ƙarshen karɓa ta hanyar cikas na yau da kullun (kamar: tubali, siminti, ciyawa, da sauransu). Ana tattara hasken da aka mayar zuwa ƙarshen karɓa kuma an mayar da shi siginar lantarki kuma an aika shi zuwa tsarin sarrafa sigina. Tsarin sarrafa sigina yana tantance ko akwai ɗigon iskar gas a cikin yanayin da aka gwada ta hanyar gano ƙarfin shan hasken laser kuma yana nuna yawan iskar gas a cikin kayan aikin auna nesa a cikin raka'a na ppm-m ko %vol. Laser ɗin da ake gani a lokaci guda yana auna nisan daga kayan aikin zuwa wurin tunani kuma yana nuna yawan iskar gas a lokaci guda. Saboda ƙa'idar cewa iskar gas (kamar methane) tana da tasirin sha akan takamaiman raƙuman laser, wannan samfurin yana amsawa ne kawai ga takamaiman iskar gas (kamar methane) kuma ba zai haifar da ƙararrawa ta ƙarya ba saboda tsangwama daga wasu iskar gas, ƙura, tururin ruwa, da sauransu, wanda ke inganta daidaiton ganowa sosai kuma yana guje wa ma'aunin ƙarya. Ana amfani da kayan aikin gano methane da carbon monoxide na JJT4-1000 galibi ta hanyar gano ƙasa.
