1.PT100 abenzi bobushushu boluvozidla ngokusetyenziswa kunye nezixhobo zokubonisa, izixhobo zokurekhoda, izibalo zombane, njl njl. Ukulinganisa ngokuthe ngqo ubushushu bolwelo, umphunga kunye negesi ephakathi kunye nomphezulu oqinileyo kuluhlu lwe -200 ° C ~ 500 ° C kwiinkqubo ezahlukeneyo zemveliso.Ukugweba ukuba ilungile okanye imbi, sebenzisa nje i-multimeter yedijithali ukuyilinganisa.
2. Uphawu lwe-PT100 yeqondo lokushisa kukuba ii-terminals ezimbini zokuphuma (ngamanye amaxesha i-multi-terminal) zixhunywe kunye ne-multimeter (nangona kukho ixabiso elithile lokumelana).Ukuba isiphaluka esivulekileyo siya kuba sibi, ngokungathandabuzekiyo linyathelo lokuqala kwisigwebo sangempela.Ixabiso lokumelana nokuxhatshazwa kwe-thermal lisisigxina.Ngokomzekelo, iqondo lokushisa eliqhelekileyo le-PT100 lijikeleze i-110 ohms, kwaye iqondo lokushisa eliqhelekileyo le-CU50 lijikeleze i-55 ohms.Imveliso ye-thermocouple yixabiso lombane.Kwiqondo lobushushu elithile, iya kukhupha isignali yombane ngokubanzi ezimbalwa ukuya kumashumi eemilivolthi, ezinokulinganiswa ngefayile yombane yemultimeter.
3. I-voltage ye-output ye-thermocouple yi-mV embalwa kuphela, kuxhomekeke ekuchanekeni kwe-multimeter.I-multimeter yedijithali ingasetyenziselwa ukulinganisa okurhabaxa kunye nokugweba.Imveliso ye-thermocouple i-odolo ye-millivolts.Akunakwenzeka ukufumanisa imveliso yakhe nge-multimeter, kodwa inokulinganiswa ngokuqhubekayo kwayo.Kwiimeko ezininzi, ngokude nje ukuba inxalenye ye-galvanic (apho iingcingo ezimbini zidibeneyo) zixhunyiwe, akukho i-oxidation, akukho monakalo, kwaye ngokuqhelekileyo akukho ngxaki.Ngoko kwangaxeshanye, inokukhutshwa kwi-sheath ukuze ihlolwe ngokubonakalayo.Ukujonga ngokwenene, kuyimfuneko ukusebenzisa umgangatho we-thermocouple ukuthelekisa kunye nokulinganisa ixabiso le-millivolt eliphumayo.
4. Oku kungasentla yindlela yokufumanisa ukuba ingaba iPT100 inzwa yobushushuyimveliso eqhelekileyo.Ndiyathemba ukunceda wonke umntu.Ukuba unayo nayiphi na imibuzo, ungaqhagamshelana nabasebenzi bethu bezobugcisa.
