Kuhambo lwam lokusebenza ngezixhobo zemozulu ezahlukeneyo kunye neenkqubo, iiprobe zokufuma zibe yinxalenye yesixhobo sam. Ezi zixhobo, zisetyenziselwa ukulinganisa ukufuma okuhambelanayo, zidlala indima ebalulekileyo kumacandelo ahlukeneyo, ukusuka kwiinkqubo zemeteorology kunye neHVAC ukuya kugcino lobugcisa kunye nokusetyenziswa kwezolimo. Ukufuma okuzalanayo (RH), okubonisa ubungakanani bokufuma obukhoyo emoyeni xa kuthelekiswa nowona mlinganiselo uphezulu obunokuwubamba kwiqondo lobushushu elithile, yiparameter ebalulekileyo kula macandelo. Umlinganiselo ochanekileyo unokwenza wonke umahluko ekugcineni iimeko ezifanelekileyo zenkqubo okanye ukuqikelela iipatheni zemozulu.
Ukubaluleka kokufundwa kwe-RH kuye kwandikhokelela ekubeni ndichithe ixesha elininzi ndifunda kwaye ndisebenza ngeprobes zokufuma. Kuwo onke amava am, ndiye ndafumanisa ukuba ezi zixhobo, ngelixa ziphucuke kakhulu, azisoloko zingenasiphako ekufundeni kwazo. Ngokufana naso nasiphi na esinye isixhobo sokulinganisa, badinga ukuphathwa ngononophelo, ukulungelelaniswa rhoqo, kunye nokuqonda okucacileyo kwemigaqo kunye nemida yabo. Ndijoyine njengoko siphengulula kwihlabathi leeprobe zokufuma kwaye sifumanise ukuba zingachaneka kangakanani na xa kufikelela kumlinganiselo we-RH.
Ukuqonda indlela i-Humidity Probes esebenza ngayo
Ukwenzela ukulinganisa ukuchaneka kweiiprobe zokufuma, ndifumanise ukuba kubalulekile ukuqonda imigaqo esisiseko sokusebenza kwazo. Uninzi lwezinzwa zokufuma zisebenzisa i-capacitive, resistive, okanye i-thermal conductivity ubuchule bokubona utshintsho kumswakama womoya. Apha, ndiza kugxila ikakhulu kwi-capacitive probes, ephakathi kwezona zisetyenziswa kakhulu ngenxa yobuntununtunu obugqwesileyo, uzinzo lwexesha elide, kunye nokuchasana nezinto ezingcolisayo.
