Temperature Coefficient ukumelana

Mayelana umphumela umumo wokwakha ukwazi, cishe zonke. Noma kunjalo, sezwa ngalo. Ingqikithi lo mphumela wukuthi ngesikhathi lokususa 273 ° C ukungawi umqhubi ukugeleza zamanje kulahleka. Kakade omunye lesi sibonelo kwanele ukuba baqonde ukuthi kukhona kwencika yayo phezu lokushisa. Futhi lokhu kwencika uchaza ipharamitha ekhethekile - lokushisa Coefficient ukumelana.

Noma yimuphi umqhubi kuvimbela therethrough esilazayo zamanje. Lokhu kuphikiswa kunina ngamunye conductive sika ehlukile, kunqunywa izici eziningi esingokwemvelo nendaba ethile, + kodwa ngeke okwengeziwe okusekhasini lokhu. Isithakazelo okwamanje kwencika yayo phezu lokushisa kanye nesimo lobu buhlobo.

Babashayeli zamanje kagesi ngokuvamile isinyathelo izinsimbi, yini ukwandisa ukwanda lokushisa ukumelana, kuyilapho ngincipha ke incipha. Ubukhulu yoshintsho ngayinye 1 ° C, futhi ubizwa ngokuthi Coefficient lokushisa yokumelana, noma TCR esifushanisiwe.

TCR Inani kungenzeka emihle noma emibi. Uma kuwukuthi omuhle ke ukwanda lokushisa ka umqhubi ukumelana inyuka, uma omubi ke incipha. Sekuyisikhathi eside iningi izinsimbi ezisetshenziswa njengoba babashayeli kagesi zamanje, TCR omuhle. Omunye babashayeli engcono liyithusi, Coefficient lokushisa ukumelana zethusi akuyona ukuthi kangcono, kodwa uma iqhathaniswa nezinye babashayeli, ke lincane. Wena nje kufanele ukhumbule ukuthi ukubaluleka kwengosi kuba TCS kunquma ukuthi ushintsho nemingcele kwemvelo kuzoba yinani ukumelana naye. ushintsho lakhe zibaluleke ngaphezu isici emikhulu.

a kwencika okunjalo lokushisa ukumelana kufanele kucatshangelwe lapho ukuklama imishini elekthronikhi. Iqiniso lokuthi imishini kufanele isetshenziswe nganoma yisiphi izimo kuma, izimoto ofanayo wokusebenza kusukela -40 ° C kuya + 80 ° C. Baningi electronics emotweni, futhi uma ungenalo acabangele ngokunzulu komthelela kwezendalo umsebenzi izakhi wesifunda, ungase ubhekana nesimo lapho kweyunithi electronic usebenza emihle ngaphansi kwezimo ezivamile, kodwa ongafuni ukusebenza lapho zihlatshwa okushisa aphansi noma ephakeme.

Kuyinto lokhu kwencika phezu izimo zemvelo uvumele Onjiniyela at okuklama yayo apharathasi usebenzisa nemingcele wesifunda Coefficient izibalo lokushisa ukumelana naye. Kukhona amatafula ngedatha ngoba TCR zokwakha kanye namafomula Ukubalwa okuyinto ukwazi TCS kungaba azimisele ukubaluleka ukumelana kunoma isiphi isimo futhi acabangele izindlela kungenzeka wokusebenza izikimu ushintsho yayo. Kodwa ukuqonda ukuthi TCS okwamanje awadingekile kungekho amafomula noma amatafula.

Kufanele kuqashelwe ukuthi kukhona izinsimbi enenani elincane kakhulu TCS, futhi asetshenziswa womshini resistors, ogama kwemigomo emvelweni ixhomeke wavuma.

Temperature Coefficient ukumelana ingasetshenziswa hhayi kuphela umphumela iyehla iyenyuka nemingcele kwemvelo, kodwa futhi ngoba lokushisa nesilinganiso. Yikuphi kwanele ulinganise ukumelana. Ukwazi izinto eye evezwa, amatafula kungaba azimisele, okuyinto lokushisa sifana ukumelana elinganisiwe. Nokho, njengoba kungenzeka imitha enjalo kufanele isetshenziswe wire yethusi abavamile, kuyodingeka usebenzise kakhulu nesilonda ngesimo, isibonelo, ohlobo lwe.

Konke okungenhla awubhekene ngokugcwele yonke imibuzo ukusetshenziswa Coefficient lokushisa ukumelana naye. Kukhona ezinye amathuba ezithakazelisayo kakhulu kwesicelo ezihlobene nale isici e Semiconductors, electrolyte, kodwa futhi lokho equkethwe, kwanele ukuqonda umqondo TCS.
