Waya yekutsiva iwaya mbiri dzine insulating layer ine kukosha kwakafanana ne thermoelectromotive force ye matched thermocouple mune imwe tembiricha range (0~100°C). Zvikanganiso zvinokonzerwa nekuchinja kwetembiricha panosangana. Mupepeti anotevera achakuudza kuti waya yekutsiva ye thermocouple chii, kuti thermocouple compensation wire chii, uye kuti thermocouple compensation wire inorongwa sei.
1. Waya ye thermocouple compensation imhando ipi?
Waya yekupa mubhadharo inoda kuti maerekitirodhi akanaka neasina kunaka ave akafanana nezvinhu zvakanaka neasina kunaka zvethermocouple. Mathermocouple emhando yeK-type i nickel-cadmium (yakanaka) uye nickel-silicon (yakaipa), saka zvichienderana neyakajairwa, waya dzekupa mubhadharo dzenickel-cadmium-nickel-silicon dzinofanira kusarudzwa.
2. Chii chinoshanda newaya ye thermocouple compensation
Ndeyekuwedzera electrode inopisa, kureva, mugumo unotonhora we thermocouple inofambiswa, uye kubatana nechishandiso chekuratidzira kuti ugadzire sisitimu yekuyera tembiricha. Shandisa zvakaenzana mwero wenyika weIEC 584-3 "Thermocouple Part 3 - Compensation Wire". Zvigadzirwa izvi zvinonyanya kushandiswa mumidziyo yakasiyana-siyana yekuyera tembiricha, uye zvave zvichishandiswa zvakanyanya musimba renyukireya, peturu, makemikari, simbi, simba remagetsi nedzimwe nzvimbo.
3. Kupatsanurwa kwewaya dzekubhadhara thermocouple
Muchidimbu, yakakamurwa kuva mhando yekuwedzera uye mhando yekupa. Maumbirwo emakemikoro emhando yekuwedzera akafanana neeaya ethermocouple yakabatana, saka thermoelectric potential yakafananawo. Inomiririrwa ne "X" mumuenzaniso, uye maumbirwo emakemikoro emhando yekubatanidza akafanana. Yakasiyana nethermocouple yakabatana, asi mukushanda kwayo tembiricha, thermoelectric potential iri pedyo ne nominal value yethermoelectric potential yethermocouple yakabatana, iyo inomiririrwa ne "C" mumuenzaniso.
Kururama kwemubhadharo kwakakamurwa kuita giredhi rakajairika uye giredhi rechokwadi. Chikanganiso mushure mekuripa giredhi rechokwadi chinowanzova hafu chete yegiredhi rakajairika, iro rinowanzo shandiswa munzvimbo dzine zvinodiwa pakuyera kwakakwirira. Semuenzaniso, kune waya dzemubhadharo dzenhamba dzeS neR dzekupedzisira, kushivirira kwegiredhi rechokwadi i±2.5°C, uye kushivirira kwegiredhi rakajairika i±5.0°C; kune waya dzemubhadharo dzenhamba dzeK neN dzekupedzisira, kushivirira kwegiredhi rechokwadi i±1.5°C, kushivirira kwegiredhi rakajairika i±2.5℃. Mumuenzaniso, giredhi rakajairika harina kunyorwa, uye giredhi rechokwadi rinowedzerwa ne "S".
Kubva pakupisa kwekushanda, yakakamurwa kuva kushandiswa kwakajairika uye kushandiswa kunodzivirira kupisa. Kupisa kwekushanda kwakajairika i0 ~ 100 °C (zvishoma i0 ~ 70 °C);
Pamusoro pezvo, nharembozha inogona kukamurwa kuita waya dzekugadzirisa tambo imwe chete uye dzakawanda (dzakapfava), uye inogona kukamurwa kuita waya dzekugadzirisa dzakajairika uye dzakadzivirirwa zvichienderana nekuti dzine jira rekudzivirira here, uye kunewo waya dzekugadzirisa dzemasekete akachengeteka mukati menguva dzakatsaurirwa kuzviitiko zvisingaputike.
