Uburyo bwa PT100 bwo gufunga insinga: Itandukaniro rigaragara hagati ya sisitemu z'insinga ebyiri, iz'insinga eshatu, n'iz'insinga enye mu kanya gato
Uburyo butari bwo bwo gufunga insinga kuri Sensor ya Pt100s zishobora gutuma ubushyuhe buhindagurika cyane—ikibazo gikomeye mu nganda. Injeniyeri nyinshi zihuza insinga ebyiri mu gihe cyo kuzishyiraho, bigatuma ubuziranenge bwo gupima budashira; nyuma yo gukemura ibibazo byinshi ni bwo bamenya ko ikibazo kiri mu buryo bwo kuzigama insinga. Iyi nkuru isobanura neza itandukaniro riri hagati ya sisitemu z'insinga ebyiri, iz'insinga eshatu, n'iz'insinga enye kugira ngo bigufashe kwirinda ingorane zitari ngombwa.
Kuki uburyo bwo gukoresha insinga bugira ingaruka ku buryo buboneye?
Kuri 0°C, ubushobozi bwo guhangana na Sensor ya Pt100 ni 100 Ω gusa; kuri buri mpinduka y'ubushyuhe bwa 1°C, ubukana bwayo buhindukaho hafi 0.385 Ω. Niba ubukana bw'insinga ari 1 Ω (kuri metero 10 z'insinga isanzwe), bitera ikosa ryo gupima ubushyuhe rya hafi 2.6°C. Kubera iyo mpamvu,Kurandura ingaruka z'ubudahangarwa bw'icyuma ni cyo kintu cy'ingenzi kigomba kwitabwaho mu bijyanye n'insinga za PT100.
Sisitemu y'imirongo ibiri: yoroshye kandi ifite ubunyangamugayo bwo hasi
Insinga ebyiri gusa ni zo zihujwe, hamwe na sensor n'igikoresho bihujwe mu buryo bukurikiranye. Akamaro ni insinga zoroshye; ikibi ni uko ubukana bw'insinga bwongerwa ku gaciro kapimwe kandi ntibushobora gukurwaho. Iyi genamiterere ikwiriye gusa intera ngufi n'ikoreshwa bifite ubuziranenge buke (± 5°C byemewe).
Sisitemu y'imirongo itatu: Igisubizo gikunze kugaragara mu nganda
Huza insinga eshatu, imwe muri zo ikoreshwa mu kwishyura ubukana bw'insinga. Iri hame rikubiyemo gushyira insinga zingana uburebure muri buri ruhande rw'ikiraro, bityo ugakuraho ubukana bw'insinga. Ubu ni bwo buryo bwa PT100 bwo gukoresha insinga bukoreshwa cyane mu nganda, bugera ku buziranenge bwa ± 0.5°C n'urugero rwo gupima rwa metero mirongo.
Sisitemu y'imirongo ine: ubuziranenge bwo hejuru
Huza insinga enye: ebyiri zo gupima isoko y'amashanyarazi idahinduka n'izindi ebyiri zo gupima voltage. Kubera ko umuriro uri mu gice cyo gupima voltage ari hafi zeru, ubwiyongere bw'amashanyarazi ntibutera kugabanuka k'amashanyarazi, bigakuraho burundu amakosa ajyanye n'amashanyarazi. Ubuziranenge bwo gupima bugera kuri ± 0.1°C, bigatuma ikoreshwa muri laboratwari no mu gupima.
Ni gute wahitamo muri ubwo buryo butatu bwo gufunga insinga?
| uburyo bwo guhuza | Umubare w'insinga | gutungana | Intera ikurikizwa | Ibintu Bisanzwe |
| sisitemu y'insinga ebyiri | Ibice 2 | ± 5℃ | | Inzogera yoroshye |
| sisitemu y'insinga eshatu | Ibice 3 | ± 0.5℃ | Metero nyinshi | kugenzura ibikorwa by'inganda |
| sisitemu y'insinga enye | Ibice 4 | ± 0.1℃ | hekitometero + | Gupima Laboratwari |
Inama yo guhitamo: Ku 90% by'inganda, sisitemu y'insinga eshatu irahagije. Sisitemu y'insinga enye ikenewe gusa kugira ngo igenzurwe neza; irinde gukoresha sisitemu y'insinga ebyiri igihe cyose bishoboka.
Mbere yo gufunga insinga, banza wemeze sisitemu y'insinga igikoresho cyawe gikoresha kugira ngo wirinde ko insinga zihinduka nyuma yo kurangiza. Ku bibazo byose bijyanye no guhitamo cyangwa gufunga insinga, nyamuneka gisha inama itsinda ryacu rya tekiniki kugira ngo riguhe ibisubizo by'inzobere.
Igereranya ry’uburyo butatu bwo gufunga insinga kugira ngo PT100 platine ikomeze ubushyuhe Igipimo cy'ubushyuhe
