Ehe,thermocouple wayainogona kuwedzerwa, asi zvakati wandei zvakakosha zvinofanirwa kutariswa kuti ive nechokwadi chekuyera tembiricha uye kuvimbika kwehurongwa. Kunzwisisa zvinhu izvi hazvingobatsire iwe kuita sarudzo ine ruzivo chete asi zvakare kuratidza kuchinjika uye kuchinjika kwezvinhu zvedu zvemhando yepamusoro thermocouple waya zvigadzirwa.
Thermocouples inoshanda yakavakirwa paSeebeck mhedzisiro, apo mutsauko wetembiricha pakati pesimbi mbiri dzakasiyana unoburitsa simba re electromotive (EMF). Paunenge uchiwedzera waya dze thermocouple, zvakakosha kushandisa waya dzekuwedzera dzakagadzirwa nezvinhu zvine zvakafanana thermoelectric zvivakwa kune yekutanga thermocouple waya. Izvi zvinova nechokwadi chekuti EMF inogadzirwa ne tembiricha gradient pamwe nehurefu hwakareba inoramba ichienderana neiyo yekutanga thermocouple maitiro.
Kambani yedu inopa huwandu hwakakwana hwepamusoro - chaiyo thermocouple yekuwedzera waya. Aya mawaya ekuwedzera anogadzirwa kune akasimba maindasitiri zviyero, kuve nechokwadi chekubhadhara kwakanyanya tembiricha uye kushomeka kwechiratidzo. Anowanikwa mumhando dzakasiyana-siyana, sengeJ, K, T, E, S,uyeR, iyo inogona kunyatsoenderana nemhando dzakasiyana dze thermocouple mumusika. Zvishandiso zvinoshandiswa mumawaya edu ekuwedzera zvinopokana neoxidation uye corrosion, zvichipa kugadzikana kwenguva refu munzvimbo dzakasiyana dzekushanda.
Kana zvasvika kune chaiwo matanho ekushanda ekuwedzera waya dze thermocouple, chekutanga, iwe unofanirwa kucheka iyo yekutanga thermocouple waya panzvimbo yakakodzera neyakapinza waya yekucheka. Zvadaro, bvisa anenge 1 - 2 cm ye insulation layer pamucheto wakachekwa wewaya yepakutanga uye waya yekuwedzera uchishandisa waya strippers. Zvadaro, monera tambo dzesimbi dzisina chinhu dzewaya yepakutanga newaya yekuwedzera pamwe chete zvakasimba, uchiita kuti magetsi abatane zvakanaka. Mushure maizvozvi, shandisa simbi yakasungirirwa uye solder kuti utengese chikamu chakamonyoroka, uchiwedzera kuvimbika kwekubatana. Pakupedzisira, vhara chibatanidzwa chakatengeswa nekupisa - shrink tubing uye shandisa kupisa nepfuti inopisa kuderedza tubing, kupa kudzivirira nekudzivirira.
Kune maturusi akakosha uye zvinhu zvinodiwa, kunze kweaya ataurwa ekucheka waya, waya anobvisa, soldering iron, solder, uye kupisa - shrink tubing, ungangoda multimeter yekutarisa kuenderera kwemagetsi kwewaya yakatambanudzwa usati waiswa. Kambani yedu inogona kupa seti yakazara yezvishandiso pamwe neiyo thermocouple waya uye ekuwedzera waya zvigadzirwa, zvichikuchengetedza iwe dambudziko rekuzvitsvaga zvakasiyana.
Mushure mekuwedzera iyo thermocouple waya, calibration inodiwa kuti ive nechokwadi chekuyera tembiricha. Imwe yakajairika nzira yekuenzanisa ndeye kushandisa calibrated tembiricha sosi. Isa iyo thermocouple junction mune inozivikanwa - tembiricha nharaunda, yakadai seyakaoma - block calibrator kana choto chine tembiricha yakagadzikana. Wobva wayera iyo voltage yekubuda kweiyo thermocouple uchishandisa chaiyo dhijitari multimeter. Enzanisa iyo yakayerwa voltage neyakajairwa voltage - tembiricha tafura inoenderana neiyo thermocouple mhando. Kana paine kutsauka, gadzirisa kuyerwa hurongwa kana chiyero chekuenzanisa zvinoenderana nekupokana ukoshi. Yedu tekinoroji tsigiro timu inogona kupa yakadzama calibration gwara kuti ive nechokwadi chekuti unogona kupedzisa iyo calibration maitiro mushe.
Pamusoro pekushandisa waya dzekuwedzera dzakafanira, kuisirwa kwakaringana kwakakosha zvakare. Mawedzero akaiswa zvisina kunaka anogona kuunza kumwe kuramba, ruzha, uye kukanganisa. Zvigadzirwa zvedu zvinouya neyakadzama yekuisa nhungamiro, uye timu yedu yekutsigira tekinoroji inogara yakagadzirira kukubatsira chero kumisikidza - ine chekuita nemibvunzo.
Imwe mukana wezvigadzirwa zvedu zvewaya thermocouple ndeyekugara kwayo. Yakagadzirwa kubva kumhando yepamusoro-giredhi zvinhu, inokwanisa kumirisana nemamiriro ekunze akaomarara, kusanganisira tembiricha yepamusoro, hunyoro, uye kuratidzwa kwemakemikari. Izvi zvinoreva kuti kunyange kana dzawedzerwa, waya dzedu dze thermocouple dzinochengetedza kushanda kwakadzikama pamusoro pehupenyu hurefu hwebasa.
Mukupedzisa, kuwedzera waya ye thermocouple kunogoneka, uye neyedu yakavimbika thermocouple waya uye ekuwedzera waya zvigadzirwa, pamwe neakakwana masevhisi ekutsigira, unogona nechivimbo kuwedzera tembiricha yako yekuyera masisitimu. Zvingave zvekushandiswa kwemaindasitiri, tsvakiridzo yesainzi, kana mamwe minda, zvigadzirwa zvedu zvinopa mhinduro dzakaringana, dzakagadzikana, uye dzinogara kwenguva refu kune tembiricha yako - zvido zvekunzwa.
