Iyiphi ikhebula le-thermocouple?

Intambo yesinxephezelo i-pair of izintambo ngesendlalelo esifanayo esinenani elifanayo eliphakeme njengamandla we-thermoelectromotive we-thermococouple efanisiwe ebangeni elithile lokushisa (0 ~ 100 ° C). Amaphutha ngenxa yokushintsha kokushisa emhlanganweni. Umhleli olandelayo uzokwethula kini ukuthi iyiphi impahla yerekisini ye-thermocouple, imuphi umsebenzi we-thermocouple isinxephezelo sentambo, kanye nokuhlukaniswa kwentambo yesinxephezelo se-thermocouple.

Intambo yesinxephezelo esijwayelekile idinga ama-elekthrothi amahle futhi abi afanayo nezinto ezinhle nezingezinhle ze-thermocouple. I-K-Type Thermocouples iyi-nickel-cadmium (enhle) ne-nickel-silicon (negative), ngakho-ke ngokwejwayelekile, izintambo zesinxephezelo se-nickel-cadmium-nickel-niilmium kufanele zikhethwe.
2. Yini umsebenzi we-thermocouple isinxephezelo sentambo
Kuzokwelula i-electrode eshisayo, okungukuthi, ukuphela okubandayo kwe-thermococouple ephathekayo, futhi uxhumane nethuluzi lokubonisa ukwakha uhlelo lokulinganisa lokushisa. Ngokufanayo amukele izinga likazwelonke le-IEC 584-3 "Thermocouple Ingxenye 3 - I-Referetion Wire". Imikhiqizo isetshenziswa ikakhulukazi kumadivayisi ahlukahlukene okulinganisa lokushisa, futhi isetshenziswe kabanzi emandleni enuzi, uphethroli, amakhemikhali, metallurgy, amandla kagesi neminye iminyango.
3. Ukuhlukaniswa kwezintambo zesinxephezelo se-thermocouple
Ngokuyinhloko, ihlukaniswe ngohlobo lwengenwe nohlobo lwesinxephezelo. Ukwakheka kwamakhemikhali okuhlangene kocingo lwe-alloy lohlobo lwengemuva kuyafana nalokho kwe-thermococople eshadile, ngakho-ke amandla we-thermoelectric naye afanayo. Imelelwa yi- "X" kumodeli, kanye nokwakheka kwamakhemikhali okuhlangene kocingo lwe-alloy yohlobo lwesinxephezelo kuyafana. Ihlukile ku-thermocople eshadiwe, kepha ebangeni lokushisa layo, amandla we-thermoelectric asondelene nenani eliphakeme lamandla we-thermoelectric we-thermococople ehambisanayo, emelelwa yi-"C" kumodeli.
Ukunemba kwesinxephezelo kuhlukaniswe ebangeni elijwayelekile nelinembile. Iphutha ngemuva kokunxeshezelwa kwebanga le-imeyili ngokuvamile kuphela ingxenye yebanga elijwayelekile, elivame ukusetshenziswa ezindaweni ezinezidingo zokunemba zokulinganisa eziphezulu. Isibonelo, ukuthola izintambo zezingxephezelo ze-S kanye nezinombolo zokuthweswa iziqu, ukubekezelela ibanga lokunemba yi- ± 2.5 ° C, futhi ukubekezelela ibanga elijwayelekile yi- ± 5.0 ° C; Ngezintambo zesinxephezelo sezinombolo ze-K ne-N iziqu, ukubekezelela ibanga lokunemba yi- ± 1.5 ° C, ukubekezelela ibanga elijwayelekile yi- ± 2.5 ℃. Emodeli, ibanga elijwayelekile alimakwa, futhi ibanga lokunemba lingezwa ngo- "S".
Ukusuka ekushiseni kokusebenza, ihlukaniswe ngokusetshenziswa okujwayelekile nokusetshenziswa kokuvikelwa kokushisa. Ukushisa okusebenzayo kokusetshenziswa okujwayelekile kungu-0 ~ 100 ° C (ambalwa angu-0 ~ 70 ° C);
Ngaphezu kwalokho, i-wire core ingahlukaniswa ibe yi-single-strand ne-multi-core) izintambo zesinxephezelo, futhi ingahlukaniswa izintambo zesinxephezelo esijwayelekile futhi esivikelekile ngokuya ngesendlalelo sokuvikela, futhi kukhona izintambo zesiyingi eziphephile ezinikezelwe izikhathi zokufakazelwa.
