Waya yekuripa iwaya mbiri dzine insulating layer ine chiyero chezita chakafanana neiyo thermoelectromotive force of the matched thermocouple mune imwe tembiricha renji (0~100°C). Zvikanganiso nekuda kwekushanduka kwetembiricha pajunction. Mupepeti anotevera achakuzivisai kuti waya yekubhadhara thermocouple chii, kuti thermocouple compensation wire inoshanda sei, uye kupatsanurwa kwewaya yekubhadhara thermocouple.
1. Chii chinonzi thermocouple compensation wire?
Iyo general compensation waya inoda kuti maelectrodes akanaka uye asina kunaka ave akafanana neakanaka uye asina kunaka zvinhu zve thermocouple. K-mhando thermocouples nickel-cadmium (positive) uye nickel-silicon (negative), saka maererano nechiyero, nickel-cadmium-nickel-silicon compensation waya dzinofanira kusarudzwa.
2. Chii chinonzi thermocouple compensation wire
Iyo ndeyekuwedzera iyo inopisa electrode, ndiko kuti, iyo inotonhora kupera kweiyo mobile thermocouple, uye kubatanidza nechiridzwa chekuratidzira kugadzira tembiricha yekuyera system. Yakaenzana tora chiyero chenyika cheIEC 584-3 "Thermocouple Chikamu 3 - Kubhadhara Waya". Zvigadzirwa zvinonyanya kushandiswa mumhando dzakasiyana dzekuyeresa tembiricha, uye zvakashandiswa zvakanyanya musimba renyukireya, peturu, makemikari, simbi, simba remagetsi nemamwe madhipatimendi.
3. Kurongwa kwewaya dzekubhadhara thermocouple
Muchidimbu, yakakamurwa kuva rudzi rwekuwedzera uye rudzi rwemuripo. Iyo yezita remakemikari kuumbwa kweiyo alloy waya yemhando yekuwedzera yakafanana neyeiyo inofananidzwa thermocouple, saka iyo thermoelectric kugona kwakafanana. Iyo inomiririrwa ne "X" mumuenzaniso, uye mazita emakemikari emhando yealloy wire yemhando yekubhadhara yakafanana. Iyo yakasiyana neinofananidzwa thermocouple, asi mukushanda kwayo kwekushisa kwekushanda, simba re thermoelectric riri pedyo nekukosha kwezita rekukwanisa kwe thermoelectric ye thermocouple inofananidzwa, iyo inomiririrwa ne "C" mumuenzaniso.
Kurongeka kwemuripo kwakakamurwa kuita giredhi rakajairwa uye giredhi chairo. Iko kukanganisa mushure mekubhadharwa kwegiredhi chaiyo inowanzoitika hafu yegiredhi yakajairika, iyo inowanzo shandiswa munzvimbo dzine kuyerwa kwepamusoro zvinodiwa. Semuenzaniso, kune waya dzemuripo wenhamba dzeS uye R dzekupedza kudzidza, kushivirira kwegiredhi chaiyo ndeye ± 2.5 ° C, uye kushivirira kwegiredhi rakajairwa ± 5.0 ° C; pawaya dzemuripo wenhamba dzekupedza kudzidza K neN, kushivirira kwegiredhi chairo ± 1.5 ° C, kushivirira kwegiredhi rakajairwa ± 2.5 ℃. Mumuenzaniso, giredhi rakajairwa harina kunyorwa, uye giredhi chairo rinowedzerwa ne “S”.
Kubva pane tembiricha yekushanda, yakakamurwa kuva kushandiswa kwakawanda uye kushandiswa kwekudzivirira kupisa. Kushanda tembiricha yekushandiswa kwese kuri 0 ~ 100 °C (mashoma ari 0 ~ 70 °C);
Uye zvakare, iyo musimboti wewaya inogona kupatsanurwa kuita imwe-strand uye yakawanda-core (soft waya) waya yekuripa, uye inogona kukamurwa kuita akajairwa uye akadzivirirwa waya dzemuripo zvichienderana nekuti ane chivharo chekudzivirira, uye kune zvakare waya dzekuripira. masekete akachengeteka mukati akazvipira kune zviitiko zvinoputika.
