Yintoni umgaqo we-PID detector?
Ukufunyanwa kwe-Photoionization (PID) kusebenzisa imitha ye-ultraviolet eveliswa yi-ionization yegesi engasebenziyo yintsimi yombane ephindaphindayo ukuze i-ionise iimolekyuli zegesi ezivavanywayo. Ngokulinganisa amandla angoku aveliswa yigesi e-ionized, kufunyanwa uxinzelelo lwegesi evavanywayo. Emva kokuba ifunyenwe, ii-ion ziphinda zihlangane zibe yigesi yokuqala kunye nomphunga, nto leyo eyenza i-PID ibe sisixhobo sokufumanisa esingonakalisiyo.

Ngokuphathelele imibuzo ngee-PID detectors?
Impendulo: Imveliso eqaliswe ngeli xesha ithatha indawo ye-PID sensor yamva nje yenkampani yethu, etshintshe isakhiwo segumbi lomoya (uyilo lwetshaneli yokuhamba) kunye nemo yokubonelela ngombane. Uyilo lwetshaneli yokuhamba olukhethekileyo lunokunciphisa ungcoliseko lokukhanya kwaye lufezekise ukusula iityhubhu zezibane ezikhululekileyo ngokucoca amanqanaba amaninzi. Ngenxa yemo yokubonelela ngombane ophakathi eyakhelwe ngaphakathi ye-sensor, ukusebenza okufutshane kuhamba kakuhle kwaye kukrelekrele ngakumbi, kwaye ukufunyanwa okudibeneyo kunye nee-sensors ezimbini kufezekisa ubomi obungaphezulu kweminyaka emi-3.
Impendulo: Imisebenzi ephambili yebhokisi yemvula kukuthintela amanzi emvula kunye nomphunga wemizi-mveliso ukuba ungachaphazeli ngqo isixhobo sokufumanisa. 2. Ukuthintela impembelelo yobushushu obuphezulu kunye neendawo zokufuma kwizixhobo zokufumanisa i-PID. 3. Vimba uthuli emoyeni kwaye ulibazise ubomi besihluzo. Ngokusekelwe kwizizathu ezingasentla, sixhobise ibhokisi engangeni mvula njengesiqhelo. Kakade ke, ukongeza ibhokisi engangeni mvula akuyi kuba nempembelelo enkulu kwixesha lokuphendula kwegesi.
Impendulo: Kufuneka kuqatshelwe ukuba iminyaka emi-3 yokungasebenzisi zixhobo ithetha ukuba i-sensor ayidingi kugcinwa, kwaye i-filter isadinga ukugcinwa. Sicebisa ukuba ixesha lokugcinwa kwe-filter lidla ngokuba ziinyanga ezi-6-12 (lifinyezwe libe ziinyanga ezi-3 kwiindawo ezinobungozi bendalo)
Impendulo: Ngaphandle kokusebenzisa ii-sensors ezimbini zokufumanisa amalungu, i-sensor yethu entsha inokufikelela ubomi beminyaka emi-2, ngenxa ye-sensor yethu entsha ye-PID (iteknoloji enelungelo lobunikazi, umgaqo jikelele unokubonwa kwicandelo lesibini). Indlela yokusebenza yokufumanisa amalungu e-semiconductor+PID inokufikelela ubomi beminyaka emi-3 ngaphandle kweengxaki.
Impendulo: a. I-Isobutene inamandla aphantsi e-ionization, ene-Io eyi-9.24V. Ingafakwa i-ionization ngezibane ze-UV kwi-9.8eV, 10.6eV, okanye 11.7eV. b. I-Isobutene inetyhefu ephantsi kwaye igesi kubushushu begumbi. Njengegesi yokulinganisa, ayibangeli monakalo mkhulu kwimpilo yabantu. c. Ixabiso eliphantsi, kulula ukuyifumana
Impendulo: Ayizukuba yonakele, kodwa ubuninzi begesi ye-VOC bunokubangela ukuba igesi ye-VOC inamathele efestileni nakwi-electrode ixesha elifutshane, nto leyo ebangela ukuba i-sensor ingaphenduli okanye inciphise uvakalelo. Kubalulekile ukucoca isibane se-UV kunye ne-electrode nge-methanol ngoko nangoko. Ukuba kukho ixesha elide legesi ye-VOC edlula i-1000PPM kwindawo, ukusebenzisa ii-PID sensors akubizi kakhulu kwaye kufuneka kusetyenziswe ii-infrared sensors ezingasasazekiyo.
Impendulo: Isisombululo esiqhelekileyo esinokufikelelwa yi-PID yi-isobutene eyi-0.1ppm, kwaye eyona sensor ye-PID ingcono inokufikelelwa yi-isobutene eyi-10ppb.
Ubukhali bokukhanya kwe-ultraviolet. Ukuba ukukhanya kwe-ultraviolet kunamandla, kuya kubakho iimolekyuli zegesi ezininzi ezinokudityaniswa ne-ion, kwaye isisombululo siya kuba ngcono ngokwemvelo.
Indawo ekhanyayo yesibane se-ultraviolet kunye nomphezulu we-electrode eqokelelayo. Indawo ekhanyayo enkulu kunye nendawo ye-electrode eqokelelayo enkulu ngokwemvelo ziphumela kwisisombululo esiphezulu.
Umsinga we-offset we-preamplifier. Okukhona umsinga we-offset we-preamplifier uncinci, kokukhona umsinga obonakalayo ubuthathaka. Ukuba umsinga we-bias we-operating amplifier mkhulu, isignali yomsinga eluncedo ebuthathaka iya kuntywiliselwa ngokupheleleyo kumsinga we-offset, kwaye isisombululo esilungileyo asinakufezekiswa ngokwendalo.
Ukucoceka kwebhodi yesekethe. Iisekethe ze-analog zithengiswa kwiibhodi zesekethe, kwaye ukuba kukho ukuvuza okukhulu kwibhodi yesekethe, imisinga ebuthathaka ayinakwahlulwa.
Ubukhulu bokumelana phakathi kombane kunye nombane. I-PID sensor ngumthombo wamandla, kwaye umbane unokwandiswa kuphela kwaye ulinganiswe njenge-voltage nge-resistor. Ukuba ukumelana kuncinci kakhulu, utshintsho oluncinci lwe-voltage alunakwenzeka ngokwendalo.
Isisombululo se-analog-to-digital converter ADC. Okukhona isisombululo se-ADC siphezulu, kokukhona isignali yombane enokulungiswa incinci, kwaye kokukhona isisombululo se-PID singcono.
